Description

This sequence change replaces phenylalanine with serine at codon 41 of the ETFB protein (p.Phe41Ser). The phenylalanine residue is highly conserved and there is a large physicochemical difference between phenylalanine and serine. This variant is present in population databases (rs746082442, ExAC 0.009%). This variant underlies the molecular finding for an individual previously diagnosed with MADD (PMID: 11420420). 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. In summary, this variant is a rare missense change with uncertain impact on protein function. Therefore, it has been classified as a Variant of Uncertain Significance.
