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

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.3789421).

The c.473A>T (p.E158V) alteration is located in exon 4 (coding exon 4) of the ANKRD2 gene. This alteration results from a A to T substitution at nucleotide position 473, causing the glutamic acid (E) at amino acid position 158 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
