Invitae RCV000822880 SCV000963703 uncertain significance Menkes kinky-hair syndrome; Cutis laxa, X-linked; X-linked distal spinal muscular atrophy type 3 2022-02-02 criteria provided, single submitter clinical testing This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 993 of the ATP7A protein (p.Ile993Val). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with ATP7A-related conditions. ClinVar contains an entry for this variant (Variation ID: 664724). 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 ATP7A 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 RCV002434020 SCV002751170 uncertain significance Inborn genetic diseases 2021-05-10 criteria provided, single submitter clinical testing The p.I993V variant (also known as c.2977A>G), located in coding exon 14 of the ATP7A gene, results from an A to G substitution at nucleotide position 2977. The isoleucine at codon 993 is replaced by valine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
