603968.0009; XERODERMA PIGMENTOSUM, VARIANT TYPE |
| Identified Mutation |
104 BP DEL, NT661 |
| Remarks |
XP5MA; "pigmented xerodermoid"; XP variant; apparently normal excision repair and a hypersensitive response of semiconservative DNA replication to UV damage; 3 similarly affected sibs; donor subject is homozygous for a 104 bp deletion at nucleotides 661_764 of the POLH gene (661_764del) resulting in a frameshift at Lys220 [Lys220fs] |
