Why is it important?
this article demonstrates that distribution of intrafamilial CYP21A2 gene mutations in Turkish children in Southeastern Turkey.
Perspectives
The genotype-phenotype relationship shows regional variability in 21-hydroxylase deficiency (21-OHD) caused by mutations in the CYP21A2 gene. This study focuses on the genotype-phenotype compatibility between patients and their siblings in a region where consanguineous marriage is common. This study showed that the most common alleles were IN2G-Q381X-R356W-P30L-V281L in the children with 21-OHD and asymptomatic siblings, and that the phenotype can be predicted from the genotype except for the P30L-V281L. This result suggests that the most common mutations in 21-OHD are similar to previous reports, but that the genotype-phenotype compatibility is good except for group C showing regional variability, and that genotyping of siblings discovered new patients
