Allelic Variant 2 |
R211X; XERODERMA PIGMENTOSUM, COMPLEMENTATION GROUP A |
Identified Mutation |
ARG211TER |
Remarks |
XP5PD; 46,XY; clinically affected; the donor subject is a compound heterozygote for two mutations in the XPA gene: one allele carries a G-to-C substitution at nucleotide 555 (555G>C) in exon 4 with results in a missplice and the second allele carries a G-to-T substitution at nucleotide 631 (631G>T) which alters the arg-211 codon (CGA) to a nonsense codon (TGA) in exon 5 [Arg211TER (R211X)]. |
