| Gene |
ERCC3 |
| Chromosomal Location |
2q21 |
| Allelic Variant 1 |
133510.0001; XERODERMA PIGMENTOSUM, TYPE B |
| Identified Mutation |
SPLICE ACCEPTOR C>A, FS; The specific mutation in the sole patient with type B xeroderma pigmentosum identified to that time was found by Weeda et al. [Cell 62: 777-791 (1990)] to be a C-to-A transversion in the splice acceptor sequence of the last intron of the only ERCC3 allele that was detectably expressed, leading to a 4-bp (GCAG) insertion in the mRNA (at position 2220) and an inactivating frameshift in the C terminus of the protein. |

| Remarks |
Clinically unaffected mother of a child with XP, group B, and features of Cockayne syndrome (GM02252); see also GM01855 (lymphoblastoid); donor subject is heterozygous for a C>A transversion in the splice acceptor sequence of the last intron of the ERCC3 gene. |
