Invitae RCV000022019 SCV000630329 pathogenic Biotinidase deficiency 2017-06-14 criteria provided, single submitter clinical testing This sequence change replaces proline with serine at codon 497 of the BTD protein (p.Pro497Ser). The proline residue is highly conserved and there is a moderate physicochemical difference between proline and serine. This variant is present in population databases (rs138818907, ExAC 0.02%). This variant has been reported as homozygous or in combination with another BTD variant in individuals affected with profound biotinidase deficiency (PMID: 10400129, 26361991, 20224900, 15776412, 19757147, 25754625, 26810761) and in combination with other variants in individuals with partial biotinidase deficiency (PMID: 10400129, 20224900). ClinVar contains an entry for this variant (Variation ID: 25094). 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. For these reasons, this variant has been classified as Pathogenic.
