Defective CHST3 causes SEDCJD

Reactome ID: R-HSA-3595172

中文名称

CHST3 缺陷导致 SEDCJD

通路描述

碳水化合物硫酸转移酶 3(CHST3)将硫酸(SO4(2-))转移到软骨硫酸蛋白中 N-乙酰半乳糖胺(GalNAc)残基的第 6 位,导致软骨硫酸(CS),这是软骨中主要的糖胺聚糖。CHST3 缺陷导致脊柱发育不良伴先天性关节脱位(SEDCJD; MIM:143095),这是一种临床表现为严重进行性脊柱侧弯(脊柱异常弯曲)、关节脱位和成年期身材矮小的骨发育不良(Unger et al. 2010)。
英文描述
Defective CHST3 causes SEDCJD Carbohydrate sulfotransferase 3 (CHST3) transfers sulfate (SO4(2-)) to position 6 of N-acetylgalactosamine (GalNAc) residues of chondroitin-containg proteins resulting in chondroitin sulfate (CS), the predominant glycosaminoglycan present in cartilage. Defects in CHST3 result in spondyloepiphyseal dysplasia with congenital joint dislocations (SEDCJD; MIM:143095), a bone dysplasia clinically characterized by severe progressive kyphoscoliosis (abnormal curvature of the spine), arthritic changes with joint dislocations and short stature in adulthood (Unger et al. 2010).
