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 Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.846

The c.8152G>T (p.G2718C) alteration is located in exon 7 (coding exon 6) of the MXRA5 gene. This alteration results from a G to T substitution at nucleotide position 8152, causing the glycine (G) at amino acid position 2718 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
