The c.187C>T (p.H63Y) alteration is located in exon 1 (coding exon 1) of the LSR gene. This alteration results from a C to T substitution at nucleotide position 187, causing the histidine (H) at amino acid position 63 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The tyrosine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 2407782). This variant has not been reported in the literature in individuals affected with LSR-related conditions. This variant is present in population databases (rs557558088, gnomAD 0.08%), and has an allele count higher than expected for a pathogenic variant. This sequence change replaces histidine, which is basic and polar, with tyrosine, which is neutral and polar, at codon 63 of the LSR protein (p.His63Tyr). 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. -
