Comment on list classification: New gene added by Zornitza Stark (Australian Genomics). This gene is associated with a relevant phenotype in OMIM and Gene2Phenotype. There is enough evidence to support a gene-disease association. This gene should be rated Green at the next review.Created: 10 May 2021, 12:41 p.m. | Last Modified: 10 May 2021, 12:41 p.m.

The marfanoid-progeroid-lipodystrophy syndrome (MFLS) is characterized by congenital lipodystrophy, premature birth with an accelerated linear growth disproportionate to weight gain, and progeroid appearance with distinct facial features, including proptosis, downslanting palpebral fissures, and retrognathia. Other characteristic features include arachnodactyly, digital hyperextensibility, myopia, dural ectasia, and normal psychomotor development.
This specific phenotype is caused by variants occurring in or affecting exon 64.
More than 5 unrelated individuals reported, rabbit model.
