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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), MATR3. . Gene score misZ 2.7297 (greater than the threshold 3.09). Trascript score misZ 3.9451 (greater than threshold 3.09). GenCC has associacion of gene with amyotrophic lateral sclerosis, distal myopathy with vocal cord weakness, amyotrophic lateral sclerosis type 21.

BP4

Computational evidence support a benign effect (MetaRNN=0.13181403).

BS2

High AC in GnomAdExome4 at 5 AD gene.
