Objective High myopia are the most common causes of irreversible blindness due to its associat ed complications. Genetic factors have been shown to play an important role in the development of high myopia. Both Mendelian and complex traits have been suggested but many genetic studie s on high myopia did not differentiate Mendelian trait from complex trait. Based on our series stud ies on high myopia in the last two decades, most early onset high myopia should be considered t o be transmitted as Mendelian trait while most high myopia in teenage students associated with e xcessive near work are more likely to be complex trait. This study aims to elucidate the genetic ba sis of Mendelian high myopia based on analysis of early onset high myopia. Method Whole exome analysis was conducted on genomic DNA from 298 probands with early on set high myopia. Variations in genes known to associated with high myopia or with other forms of retinal diseases were analyzed. Comparative variation analysis was performed in order to search for novel mutations in genes not associated with any know diseases. Result Mutations in genes suggested to be associated with high myopia were only detected in a f ew families. Comprehensive analysis of genes know to be responsible for other retinal diseases i dentified potential pathogenic mutations in 34 of 234 genes in 71 of 298(23.4%) probands. Comp arative analysis between whole exome sequencing data from the 298 probands and those from s everal cohorts with other diseases not only revealed several novel candidate genes for Mendelianhigh myopia but also suggested a few unlikely causative genes reported to be responsible for hig h myopia and other retinal diseases. Conclusion Our findings provide evidence to support that early onset high myopia is likely trans mitted as Mendelian trait. About one fourth of such high myopia might be the most significant or e arliest sign of other hereditary ocular or systemic diseases. Functional studies or generati

Objective H19 has been reported to repress proliferation as a precursor of mi R-675;however, in the present study, we found that the transcript level of mi R-675 did not correlate with H19 express ion in mouse fetal liver tissues. Thus, H19 appears to inhibit the proliferation of fetal liver cells via other molecular mechanisms. This study is used to illustrate other molecular mechanisms of H19 inhibition the proliferation of fetal liver cells. Method In this study, we found that H19 is the most strongly differentially expressed long noncodi ng RNA(lnc RNA) during liver development by real-time PCR using H19-specific primers. Moreov er, the function of H19 in fetal liver cells was explored in vitro. Genome-wide Ch IP-seq analysis w as used to elucidate the molecular mechanisms of H19 inhibition the proliferation of fetal liver cell s. Result In this study, we found that H19 is the most strongly differentially expressed long noncodi ng RNA(lnc RNA) during liver development. H19 may inhibit the proliferation of fetal liver cells by blocking the interaction between heterogeneous nuclear ribonucleoprotein(hn RNP) U and actin, which results in gene transcriptional repression. Based on Ch IP-seq analysis, we found that gene s involved in the Wnt signaling pathway are enriched among hn RNP U-binding genes. Further inv estigation demonstrated that hn RNP U has opposing effects on cell proliferation and Wnt/b-cateni n signaling pathway activity compared to H19 and that hn RNP U is very important in this process. Conclusion Our findings provide a novel understanding of the role of H19 in liver development.

Objective Non-obstructive azoospermia(NOA) is a complex, multifactorialdisease. Recent geno me-wide association studies(GWAS) have identified eight NOA susceptibility loci at genome-wid e significance of P< 5.0 X10-8 in Han Chinese from southeastern, northern, and central China. Method To better understand the role of the variants in conferring NOA risk, we selected four GW AS loci(HLA-DRA rs3129878, PRMT6 rs12097821, SOX5 rs10842262, and PEX10 rs2477686) t hat were reported before 2014 to investigate their association with NOA and their potential effects on sperm production in 1177 Han males from southwest China, including 545 patients with idiopa thic NOA and 632 controls with normozoospermia. Result The results confirmed that the HLA-DRA rs3129878 was an NOA susceptibility locus in th e present population. Along with our data, meta-analyses supported the association of the four G WAS-linked loci with NOA, whereas an additive effect of the four loci on NOA susceptibility was n ot found. Interestingly, the normozoospermic males with the risk genotypes of rs12097821 and rs3129878 + rs10842262 + rs12097821 were observed to have higher total sperm counts relative t o non-risk genotypes. Conclusion Our work suggests that the risk alleles of the genetic loci may not be via impairing sp ermatogenic ability to express susceptibility to NOA. These findings may advance our understand ing of the role of the NOA susceptibility loci, although the results need to be confirmed in larger samples.

Objective To evaluate the impact of the 5‘UTR variant on the expression of RIBC2 and the varian ce of RIBC2 expression between different genotypes in Chinese population and identify the poten tial interacting genes of RIBC2. Method The wildtype 5‘UTR sequence of RIBC2 was amplified from human genomic DNA and in serted into the psi CHECK-2 plasmid. PCR-mediated mutagenesis was conducted to construct the plasmid with mutant 5‘UTR. Luciferase activity and q PCR were evaluated to compare the expres sion efficiency between the wildtype and mutant construct in translation and transcription levels, r espectively. For population studies, the m RNA levels of RIBC2 were measured after genotyping o f this variant using 30 normal samples. Finally, stable overexpression of RIBC2 was introduced in the HEK293 T cells to investigate the impact of its interacting genes predicted by in-silico studies. Result The variant rs2272804 in 5‘UTR of RIBC2 resulted in a dramatic drop by about 83% comp ared with the wildtype luciferase activity while the m RNA level showed a relatively modest change. In vivo studies for population exhibit the same trends with the dual-luciferase assays, indicating t he variance in expression of RIBC2 in population with different rs2272804. Furthermore, we firstly reported its potential interacting genes TRAF2 and TRIM37, which lead to significant change in e xpression efficiency after overexpression by RIBC2. Conclusion This study firstly reports a functional and common variant in 5‘UTR of RIBC2 which d ramatically inhibits the expression efficiency of RIBC2 both in vivo and in vitro and identifies two i nteracting genes of RIBC2.

Objective Waardenburg syndrome（WS） is an auditory-pigmentary disorder with varying combina tions of sensorineural hearing loss and abnormal pigmentation. This study aimed to investigate m olecular pathology and provide prenatal diagnosis of Waardenburg syndrome in Chinese families. Method A total of 11 WS patients from 5 unrelated Chinese families were enrolled. A thorough cli nical examination was performed for all participants. Furthermore, WS patients underwent screening for PAX3, MITF, SOX10, SNAI2 and EDNRB mut ations using PCR-sequencing. Array-based comparative genomic hybridization（a CGH） was used for some patients whose sequence results were normal. After the genotype of the probands and their parents were identified, prenatal geneti c diagnosis was performed for family 01 and 05. Result According to the diagnostic criteria for WS, five cases were diagnosed as WS1, while the other six cases were WS2. Genetic analysis revealed three mutations including a nonsense mutat ion PAX3 c.583 C>T in family 01, a splice-site mutation MITF c.909 G>A in family 03 and a in-fram e deletion MITF c.64749 del GAA in family 05. The mutations（c.583 C>T in PAX3 and c.909 G>A in MITF） were the first time reported in Chinese people. Gene mutation failed to be found in famil y 02 and 04. The prenatal genetic diagnosis of the two fetuses was carried out and showed the tw o babies were normal. Conclusion Our results expanded the spectrum of gene mutations in China. Identification of gen e mutations in these families provided an efficient way to understand the causes of Waardenburg syndrome and improved genetic counseling.

Objective Schizophrenia(SZ) and major depressive disorder(MDD) are two common severe me ntal disorders that have arisen to public awareness in recent years. Serotonin(5-HT) receptors ha ve been implicated in the pathophysiology of psychiatric disorders especially in MDD and SZ. The aim of this study is to explore whether the variants in the 5-HT1 A and 5-HT2 A gene are suscepti ble to SZ or MDD in the Chinese Han population. Method We conducted this study by recruiting 752 schizophrenia patients, 568 major depressive disorder patients and 846 healthy control subjects in the Han Chinese samples for a case–control study. We genotyped five SNPs(rs1364043, rs10042486, rs6313, rs6311, rs17289304) within th e 5-HT1 A and 5-HT2 A gene using Mass ARRAY? technology. Result The results showed that the 5-HT1 A rs10042486 was significantly associated with SZ(Pall ele = 0.0369, Pgenotype = 0.0098). Moreover, the haplotype(C-T) composed of rs10042486 and rs1364043 showed significant difference between SZ cases and healthy controls(P = 0.0302) while another haplotype(T-G) was significant for MDD(P = 0.0247). Conclusion Our results highlight the role of the 5-HT1 A especially rs10042486 to SZ in the Chin ese Han population. There was no significant association between the 5-HT2 A gene and SZ or M DD. However, considering the limitation of incomplete SNP coverage, further genetic analysis ne ed to be performed in larger size of samples with more saturated SNP coverage and in different e thnic groups. The study shows that it is necessary to continue investigate more on the role of 5-H T1 A and further functional studies are suggested for the elucidation of its molecular mechanisms.

Objective Null mutations in the human IQCB1/NPHP5(nephrocystin-5) gene that encodes NPHP5 are the most frequent cause of Senior-Loken syndrome, a ciliopathy that is characterized by Leber congenital amaurosis and nephronophthisis. NPHP5 protein posses IQ calmodulin(Ca M)-binding motifs, localizes at the photoreceptor cilia with unknown function. In this study, we aim to develop a mouse model of Nphp5-related retinal ciliopathy and to reveal the molecular mechanisms underlying the disease. Method We generated germline Nphp5 knockout mice by placing a β-Geo gene trap in intron 4, thereby truncating NPHP5 at Leu87 and removing all known functional domains. The retinal morphology and function of Nphp5-/-mice were studied by using retinal histology, electroretinography, immunochemistry, and electromicroscopy analysis. Result At eye opening, Nphp5-/-mice exhibited absence of scotopic and photopic electroretinogram responses, a phenotype that resembles Leber congenital amaurosis. Outer segment transmembrane protein accumulation in Nphp5-/-endoplasmic reticulum was evident as early as postnatal day(P)6. EGFP-CETN2, a centrosome and transition zone marker, identified basal bodies in Nphp5-/-photoreceptors, but without fully developed transition zones. Ultrastructure of P6 and 10 Nphp5-/-photoreceptors revealed aberrant transition zones of reduced diameter. Nphp5-/-photoreceptor degeneration was complete at 1 month of age but was delayed significantly in Nphp5-/-;Nrl-/-(cone only) retina. Nphp5-/-mouse embryonic fibroblast developed normal cilia, and Nphp5-/-kidney histology at 1 year of age showed no significant pathology. Conclusion Our results demonstrated that NPHP5 is essential for photoreceptor outer segment formation but is dispensable for kidney and mouse embryonic fibroblast ciliary formation. And it suggests that the failure in photoreceptor ciliogenesis is the underlying mechanisms of IQCB1/NPHP5-related Leber congenital amaurosis.

Objective Congenital insensitivity to pain with anhidrosis（CIPA）, also known as hereditary senso ry and autonomic neuropathy type IV（HSAN IV）, is a rare autosomal-recessive disorder characte rized by insensitivity to noxious stimuli, recurrent episodes of hyperthermia, self-mutilating behavi ors and intellectual disability. Mutations in Neurotrophic tyrosine kinase receptor type 1（NTRK1） gene were demonstrated to be associated with this disorder. In this study, we described two Chin ese siblings with typical CIPA phenotypes. Mutation screening of the NTRK1 gene revealed that a novel nonsense mutation and a known splice-site mutation are responsible for this disorder. Method Clinical and genetic analyses were conducted on two Chinese siblings with typical sympt oms of CIPA including insensitivity to pain, inability to sweat and self-mutilating behaviors. Periph eral blood was collected from all the family members after giving informed consent. Examination of chromosomal karyotype was performed for both affected children. Genomic DNA was extracte d from the blood samples. All seventeen exons and intron-exon boundaries of the NRTK1 gene were amplified by PCR. The amplified DNA fragments were purified and sequenced in both directi ons using ABI 3130 Genetic Analyzer. The resulting sequences were analyzed and compared wit h the reference sequence of NTRK1（NM02529.3） in the NCBI database. Result Paternal mutation c.7 C>T found within exon 1 is a novel nonsense mutation, which result ed in a premature termination of m RNA translation. Maternal mutation c.851-33 T>A was a splice-site mutation detected within intron 7, which causes aberrant splicing and had been proved to be a pathogenic mutation Conclusion Our findings expand the known mutation spectrum of NTRK1 gene and provide insig hts into future studies related to CIPA.

Objective Micro RNAs(mi RNAs) are a class of non-coding RNAs important in posttranscriptional repressors involved in the regulation of almost every biological process. Mi RNA-mediated regulati on depends on perfect matching between the seven nucleotides of its seed region and the target sequence usually located at the 3‘ untranslated region of the regulated gene. Hence, even single changes in seed regions may affect mi RNA binding capacity and specificity. Previous studies hav e proven that genetic variations in mi RNAs, especially those in the seed regions, have profound a nd broad impacts on gene expression, phenotypic variation and disease susceptibility in human. Method For the present study, we employed a comparative bioinformatic analysis to explore the f unctional significance of sequence variation within the seed region of human mi RNAs. Result A total of 530 SNPs were mapped to the mi RNA seeds(including the known SNPs in the seed region of mi R-1304, mi R-96 and mi R-184), which are located at position 2-8 of the mature mi RNA sequences. We found that the central positions of the mi RNA seeds(positions 4, 5 and 6) contain fewer genetic variants than the peripheral positions in the seeds(2, 3, 7 and 8), indicated more evolutionary conserved and greater importance of middle seed base positions 4 to 6 in mi R NA function. Analysis of the predicted targets for reference and derived mi RNA alleles indicates that a substitution of even a single nucleotide within the seed region changes the spectrum of m R NA targets by >50%. Additionally, except for most of the genetic variations in mi RNA seed region are involved in human diseases, some SNPs are located in non-coding human adaptive accelerat ed regions after we checked for the diseases association and adaptive evolution of all SNPs in mi RNA seed region. Conclusion We suggest that functional changes of genetic variations in mi RNA seed region ma y prove very useful for understanding the disease pathogenicity an
