613815.0006; ADRENAL HYPERPLASIA, CONGENITAL, DUE TO 21-HYDROXYLASE DEFICIENCY |
| Identified Mutation |
IVS2AS,A/C>G,-13 |
| Remarks |
Only affected amongst triplets; a paternal cousin is also affected; at birth, severely virilized & elevated 17-hydroxy-progesterone; 46,XX in PBL; pt doing well on hydrocortisone; donor subject is homozygous for an A>G or C>G change at position -2 in the acceptor splice site of intron 2 resulting in an aberrant splice site being activated 7 bases upstream of the mutation in the CYP21A2 gene [IVS2-13A/C>G] |
