Genes affected

MATR3 (HGNC:6912): (matrin 3) This gene encodes a nuclear matrix protein, which is proposed to stabilize certain messenger RNA species. Mutations of this gene are associated with distal myopathy 2, which often includes vocal cord and pharyngeal weakness. Alternatively spliced transcript variants, including read-through transcripts composed of the upstream small nucleolar RNA host gene 4 (non-protein coding) and matrin 3 gene sequence, have been identified. Pseudogenes of this gene are located on chromosomes 1 and X. [provided by RefSeq, Aug 2013]

This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 761 of the MATR3 protein (p.Asn761Ser). This variant is present in population databases (rs758675030, gnomAD 0.06%). This variant has not been reported in the literature in individuals affected with MATR3-related conditions. ClinVar contains an entry for this variant (Variation ID: 581337). 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 MATR3 protein function with a negative predictive value of 80%. 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. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.2282A>G (p.N761S) alteration is located in exon 16 (coding exon 12) of the MATR3 gene. This alteration results from a A to G substitution at nucleotide position 2282, causing the asparagine (N) at amino acid position 761 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
