| Identified Mutation |
GLN645TER |
| Remarks |
Clinically affected; B.S. Registry # 169; elevated sister chromosome exchange; donor subject is homozygous for a C>T transition at nucleotide 1933 of the RECQL3 gene [1933C>T] resulting in a substitution of a termination signal for glutamine at codon 645 [Gln645Ter (Q645X)]. |
