Genes affected

XIRP1 (HGNC:14301): (xin actin binding repeat containing 1) The protein encoded by this gene is a striated muscle protein and belongs to the Xin actin-binding repeat-containing protein (XIRP) family. The protein functions to protect actin filaments during depolymerization. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2017]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.10831311).

The c.5144T>A (p.V1715D) alteration is located in exon 2 (coding exon 1) of the XIRP1 gene. This alteration results from a T to A substitution at nucleotide position 5144, causing the valine (V) at amino acid position 1715 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
