    WRN mutation Mutation in WRN causes Werner Syndrome which characteristics includes prematurely aged facies, scleroderma-like skin changes, cataracts, arteriosclerosis, subcutaneous calcification, and diabetes mellitus [McKusick et al. 1963; 5327241]. Inheritance is autosomal recessive and malignancy is frequent. THe frequency is 3 per million individuals in Japan [7460386]. Cells from a Werner heterozygote exit the cell cycle at a faster rate than do normal cells [8265666]. Loss of WRN promoter aberrant mitotic recombination [11316787]. Human
    UCHL1 mutation UCHL1 is assoicated with Parkinson's disease [9774100]. UCHL1 belongs to a family of de-ubiquitinating enzymes responsible for the hydrolysis of bonds between ubiquitin molecules and small adducts [11084366]. Decreased activity due to mutation may result in decreased labeling of abnormal proteins for clearance. Human
    PSEN1 mutation Mutations (more than 60 different) in PSEN1 are associated with Alzheimer's disease, of which all result in increased production of abnormally long amyloid beta-protein and an increase in senile plaque formation [10934557]. Human
    LMNA mutation Dominant mutation in LMNA (lamin A/C) gene cause Hutchinson-Gilford progeria syndrome (HGPS) which is rare and characterized by prematurly senile appearing skin and hair, with death from coronary artery disease often by age 10 [Gilford 1904; Hutchinson 1886; OMIM]. The median age of death in HGPS individuals is 13.4 years. A C to T transition at nucleotide 1824 is associated with HGPS [Sandra-Giovannoli et al., 2003; Eriksson et al., 2003]. The 1824C-T allele appears to act in a dominant negative manner by interfering with normal splicing, resulting in production of both the normal transcript and a transcript deleted for 150 bp at the 3' end [Sandre-Giovannoli et al, 2003]. Cultured skin fibroblasts from individuals with progeria exhibit an increased fraction of hat-labile proteins [1128606]. Gilford (1904). Ateleiosis and progeria: continuous youth and premature old age. Brit Med J 2, 914-918. Hutchinson, J. (1886). Case of congenital absence of hair, with atrophic condition of the skin and its appendages, in a boy whose mother had been almost wholly bald from alopecia areata from the age of six. Lancet 1, 923. Human
    Homozygous GH1 deletion Mean lifespan in untreated, affected individuals homozyogus for a deletion at the GH1 locus is significantly shorter (P < 0.05) than in affected siblings or the general population. Individuals homozygous for GH1 deletion demonstrate hereditary dwarfism [12915652]. Human
    ERCC8 mutation Individuals with a mutation in ERCC8 (alias CKN1) have a shortened lifespan, short stature, precociously senile appearance, retinal degeneration, optic atrophy, sensitivity to sunlight, and mental retardation [14156156]. Hypertension and renal disease are also common in ERCC8 mutants [514720]. Human
    BLM mutation BLM mutation cuases Bloom syndrom. Individuals with Bloom syndrome have a shortend life expectancy []. Death is primary due to cancer, particulary leukemia and lymphoma [German, 1992]. Bloom syndrome is not a premature aging disease. Bloom syndrome characteristics are grwoth deficiency, sun-snesitivity, telangiectatic hypo- and hyperpigmented skin, predisposition to malignancy, and chromosomal instability [5770175]. Human
    ATM mutation Individuals with ataxia-telangiectasia (AT) have a decreased lifespan, with a maximum of 52 years [3864931]. Human
