Comment on list classification: New gene added by Zornitza Stark. There are 3 unrelated families with variants in this gene; however, lipodystrophy is only described in 1 family. Adding as Red gene until further evidence is available.

I don't know

Biallelic canonical splice variants identified in monozygotic twins and another individual with similar phenotypes from 2 unrelated families. RNA studies confirmed exon skipping occurs in all affected individuals.

A separate study identified a homozygous nonsense variant in an individual with features of Neonatal progeroid syndrome/Wiedemann–Rautenstrauch syndrome. Quantitative PCR showed reduction in mRNA suggestive of NMD.

Three cases altogether but the phenotypes are very different -- may represent a spectrum with the more severe phenotypes resulting from truncating variants but further cases needed.
