We present a multigenerational family with a phenotypic spectrum of skin dyspigmentation, lipodystrophy, bony anomalies, and progeroid facies. All were found to be heterozygous for a c.11C>G (p.Pro4Arg) (P4R) mutation in the lamin A/C gene consistent with atypical progeroid syndrome. Various phenotypic associations have been reported with specific mutations in atypical progeroid syndrome, but the strength of each phenotype-genotype relationship is unknown. This report adds to the literature of patients with atypical progeroid syndrome and highlights an unusual diagnosis that may present to dermatologists.
Keywords: atypical progeroid syndrome; lamin type A; lipid metabolism; lipodystrophy; progeria.
