| Gene |
ERCC6 |
| Chromosomal Location |
10q11 |
| Allelic Variant 1 |
133540.0002; COCKAYNE SYNDROME, TYPE B; DE SANCTIS-CACCHIONE SYNDROME, INCLUDED |
| Identified Mutation |
ARG735TER; Colella et al. [Hum. Molec. Genet. 9: 1171-1175 (2000)] demonstrated homozygosity for the arg735-to-ter mutation in the ERCC6 gene in 2 sibs with de Sanctis-Cacchione syndrome (278800), a form of xeroderma pigmentosum associated with severe neurologic involvement. The authors concluded that there is no simple correlation between molecular defects in Cockayne syndrome type B and clinical features, and that other genetic and/or environmental factors may determine the pathologic phenotype. |

| Remarks |
Clinically affected; marked growth retardation without signs of the cachectic dwarfism seen in Cockayne syndrome; microcephaly, facial hyperpigmented macules and telangiectasias, spasticity of the limbs; ocular and cutaneous solar sensitivity; parents are distant relatives; affected brother is GM10905; donor subject is homozygous for a C>T transition at nucleotide 2282 (2282C>T) in the ERCC6 gene, resulting in a nonsense mutation at codon 735 [ARG735TER (R735X)]; the donor subject is also homozygous for a silent change at nucleotide 2830 [a C>T transition (2830C>T; GLY917GLY)]. |
