ARG899TER |
| Remarks |
Clinically affected; B. S. Registry # 191; typical features; elevated sister chromosome exchange; donor subject is homozygous for a C>T transition at nucleotide 2695 of the RECQL3 gene [2695C>T] resulting in a substitution of a termination signal for arginine at codon 899 [Arg899Ter (R899X)]. |
