Details

Homozygous mutation of XPD results in an extreme shortening of life-span (mean life-span = 7 months) relative to wild type (mean life-span > 24 months).

Other phenotypes: The shortened life span of the mutant mouse is accompanied by symptoms of premature aging including including osteoporosis, early graying, cachexia, and infertility [pubmed]. Mouse model for the brittle hair disorder trichothiodystrophy (TTD). Phenotypes include brittle hair, UV sensitivity, and developmental defects [pubmed].
