A novel sequence polymorphism due to a T to C transition at the third nucleotide of the codon for Cys283 of the vitamin D-binding protein (GC) gene assigned to chromosome 4q13-4q21.1 was revealed by sequence analysis. Population studies by single strand conformation polymorphism (SSCP) analysis showed this GC-283.3 site was polymorphic in a Black African population but monomorphic in a European population.
通过序列分析发现，定位于染色体4q13 - 4q21.1的维生素D结合蛋白（GC）基因中，编码半胱氨酸283的密码子第三个核苷酸处发生了T到C的转换，产生了一种新的序列多态性。采用单链构象多态性（SSCP）分析进行的群体研究表明，该GC - 283.3位点在非洲黑人群体中具有多态性，而在欧洲人群体中为单态性。
