| Remarks |
Clinically affected; B.S. Registry #20; sun sensitivity; increased sister chromatid exchange in fibroblasts; donor subject is a compound heterozygote: one allele has a deletion at nucleotide 2923 of the RECQL3 gene [2923delC] resulting in a frameshift [fs:974+23-X] and a second allele has a deletion of exon 15 resulting in a frameshift [fs:941+26-X]. |
