Labcorp Genetics (formerly Invitae), Labcorp RCV000634064 SCV000755342 uncertain significance Walker-Warburg congenital muscular dystrophy 2022-09-27 criteria provided, single submitter clinical testing This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 14 of the FKTN protein (p.Thr14Met). This variant is present in population databases (rs149033995, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with FKTN-related conditions. ClinVar contains an entry for this variant (Variation ID: 93520). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt FKTN protein function. 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.

Ambry Genetics RCV004019537 SCV004871083 uncertain significance Cardiovascular phenotype 2024-04-29 criteria provided, single submitter clinical testing The c.41C>T (p.T14M) alteration is located in exon 3 (coding exon 1) of the FKTN gene. This alteration results from a C to T substitution at nucleotide position 41, causing the threonine (T) at amino acid position 14 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
