In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: not found (cov: 32)
• Consequence: XIRP2 NM_152381.6 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.0540

Genes affected

XIRP2 (HGNC:14303): (xin actin binding repeat containing 2) Enables actin filament binding activity. Predicted to be involved in actin cytoskeleton organization and heart development. Predicted to act upstream of or within cardiac muscle tissue morphogenesis; cell-cell junction organization; and ventricular septum development. Colocalizes with focal adhesion and stress fiber.
