Labcorp Genetics (formerly Invitae), Labcorp RCV002031583 SCV002311365 uncertain significance Klippel-Feil syndrome 1, autosomal dominant; Isolated microphthalmia 4; Microphthalmia, isolated, with coloboma 6; Leber congenital amaurosis 17 2024-01-11 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 369 of the GDF6 protein (p.Asp369Gly). This variant is present in population databases (rs774573217, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with GDF6-related conditions. ClinVar contains an entry for this variant (Variation ID: 1524247). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on GDF6 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 RCV004631942 SCV005123800 uncertain significance Inborn genetic diseases 2024-05-10 criteria provided, single submitter clinical testing The c.1106A>G (p.D369G) alteration is located in exon 2 (coding exon 2) of the GDF6 gene. This alteration results from a A to G substitution at nucleotide position 1106, causing the aspartic acid (D) at amino acid position 369 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
