Genes affected

MXRA5 (HGNC:7539): (matrix remodeling associated 5) This gene encodes one of the matrix-remodelling associated proteins. This protein contains 7 leucine-rich repeats and 12 immunoglobulin-like C2-type domains related to perlecan. This gene has a pseudogene on chromosome Y. [provided by RefSeq, Mar 2010]

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.986

The MXRA5 c.7835G>C (p.Gly2612Ala) variant, to our knowledge, has not been reported in the medical literature and is absent from the general population (gnomAD v.2.1.1), indicating it is not a common variant. Computational predictors indicate that the variant is damaging, evidence that correlates with impact to MXRA5 function. Due to limited information, the clinical significance of this variant is uncertain. -
