目的:分析一例软骨–毛发发育不良(CHH)患儿的临床特征及基因变异特点。方法:回顾分析1例CHH患儿的临床资料及相关实验室检查结果,对先证者父母及其进行家系全外显子测序。结果:矮小患儿表现为生长发育迟缓,发育落后、特殊面容(头发颜色偏黄,内眦赘皮,腭弓稍高),给予生长激素治疗,生长速度改善不明显,基因测序显示患者是RMRP基因c.-90-425G>A,杂合突变,目前国内外尚未见报道。结合患儿临床表现及检查结果,诊断为CHH。结论:临床上特殊类型矮小患儿应尽早行全外显子测序和Sanger测序,以明确诊断。关键软骨–毛发发育不良,RMRP基因,身材矮小 [-rId9-]Yuxin Liu1, Jingtong Zhao2, Xiaozheng Wan3, Dexian Kong4, Kexin Gan5, Xiuqin Lyu5, Dongmei Zhang5, Boqing Ma5, Jing Liu5*, Huijuan Ma61Clinical Medical College, North China University of Science and Technology, Tangshan Hebei2Clinical College of Hebei Medical University, Shijiazhuang Hebei3Graduate School of Hebei North University, Zhangjiakou Hebei4Department of Endocrinology, Hebei Petrol China Central Hospital, Langfang Hebei5Department of Endocrinology, Hebei General Hospital, Shijiazhuang Hebei6Department of Endocrinology, The First Hospital of Hebei Medical University, Shijiazhuang HebeiReceived: Jan. 24th, 2025;accepted: Feb. 17th, 2025;published: Feb. 27th, 2025[-rId9-]AbstractObjective: To analyze the clinical features and genetic variation of a child with Cartilage-hair hypoplasia (CHH). Methods: The clinical data and laboratory test results of one child with CHH were retrospectively analyzed, and the parents of the proband and their families were sequenced by whole exon. Results: The patient presented with growth retardation, developmental lag, and special features (yellow hair color, epicanthus, and slightly high palatal arch). The patient was diagnosed as short stature in another hospital and was treated with growth hormone, with no obvious improvement in growth rate. Gene sequencing showed that the patient had RMRP gene c.-90-425G>A and heterozygous mutation, which has not been reported at home and abroad. Combined with the clinical manifestations and examination results, the patient was diagnosed as CHH. Conclusion: In patients with high suspection of a special type of short stature, early genetic tests should be carried out for a clear ***-Hair H
患者 男,42岁,主诉右膝关节肿痛2年余,曾于2012-10在当地医院就诊,诊断为滑膜炎。给予抽液,冲洗,抗生素等治疗,症状得到缓解。本次由于胀痛症状再次出现,来院就诊。入院查体:中等体型,无膝关节外伤史。右膝关节较对侧明显肿胀,有压痛,局部皮温高,浮髌实验阳性,关节活动受限。实验室检查:血、尿、便常规及血尿酸正常,血沉、类风湿3项、C反应蛋白均在正常值范围。MRI 检查显示:膝关节腔及髌上囊内可见大量积液,积液内可见多发 T1 WI 序列呈高信号,脂肪抑制 T2 WI 序列呈低信号,树枝状、绒毛状结节(图1~4)。行右膝关节关节镜滑膜切除,术后病理诊断为:滑膜树枝状脂肪瘤。
