Invitae RCV000824476 SCV000965375 uncertain significance Deficiency of hydroxymethylglutaryl-CoA lyase 2018-11-30 criteria provided, single submitter clinical testing 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 disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has been observed in an individual affected with HMG-CoA lyase deficiency (PMID: Invitae). This variant is not present in population databases (ExAC no frequency). This sequence change replaces threonine with isoleucine at codon 210 of the HMGCL protein (p.Thr210Ile). The threonine residue is highly conserved and there is a moderate physicochemical difference between threonine and isoleucine.
