Submissions by phenotype
not specified Uncertain:1
The c.1381G>A (p.A461T) alteration is located in exon 2 (coding exon 1) of the FLRT1 gene. This alteration results from a G to A substitution at nucleotide position 1381, causing the alanine (A) at amino acid position 461 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Peripheral neuropathy Uncertain:1
Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C55"). 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. ClinVar contains an entry for this variant (Variation ID: 530934). This variant has not been reported in the literature in individuals affected with FLRT1-related conditions. This variant is present in population databases (rs138289564, gnomAD 0.05%), and has an allele count higher than expected for a pathogenic variant. This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 461 of the FLRT1 protein (p.Ala461Thr). -
