Genes affected

ANKRD2 (HGNC:495): (ankyrin repeat domain 2) This gene encodes a protein that belongs to the muscle ankyrin repeat protein (MARP) family. A similar gene in rodents is a component of a muscle stress response pathway and plays a role in the stretch-response associated with slow muscle function. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Mar 2014]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=3.7439586E-6).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.689 is higher than 0.05.
