Genes affected

UFM1 (HGNC:20597): (ubiquitin fold modifier 1) UFM1 is a ubiquitin-like protein that is conjugated to target proteins by E1-like activating enzyme UBA5 (UBE1DC1; MIM 610552) and E2-like conjugating enzyme UFC1 (MIM 610554) in a manner analogous to ubiquitylation (see UBE2M; MIM 603173) (Komatsu et al., 2004 [PubMed 15071506]).[supplied by OMIM, Dec 2008]

Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 11 of the UFM1 protein (p.Arg11Gly). This variant is present in population databases (rs753228455, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with UFM1-related conditions. -
