Lipodystrophy - childhood onsetGene: VIM
Previously variants in this gene have been associated with cataracts (PMID: 26694549, 19126778). Cogne et al 2020 (PMID: 32066935) - report a de novo heterozygous variant in VIM (c.1160 T > C; p.(Leu387Pro)) causing a syndromic disorder affecting craniofacial development, peripheral nervous system, and adipose and ectodermal tissues in a 39 year old male. The variant was identified by WES. Both parents lacked the variant. Expression of human vimentin p.(Leu387Pro) in zebrafish resulted in a phenotype of perturbed body fat distribution, and craniofacial and peripheral nervous system development. Functional studies using patient-derived and transfected cells showed that the variant affects vimentin turnover and its ability to form filaments in the absence of wild-type vimentin.
