| Allelic Variant 2 |
no splice site; XERODERMA PIGMENTOSUM, COMPLEMENTATION GROUP A |
| Identified Mutation |
389G>A |
| Remarks |
XP4JO; African; positive family history; blindness due to corneal opacity; skin shows areas of hypo- and hyperpigmentation but no malignancies; offspring of consanguineous parents; donor subject is homozygous G-to-A substitution at nucleotide 389 (389G>A) in exon 3 of the XPA gene which results in no splice site. |
