Genes affected
CAPN15 (HGNC:11182): (calpain 15) This gene encodes a protein containing zinc-finger-like repeats and a calpain-like protease domain. The encoded protein may function as a transcription factor, RNA-binding protein, or in protein-protein interactions during visual system development. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.104115814).
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00019 (29/152354) while in subpopulation AFR AF = 0.000529 (22/41578). AF 95% confidence interval is 0.000358. There are 0 homozygotes in GnomAd4. There are 11 alleles in the male GnomAd4 subpopulation. Median coverage is 34. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.55G>A (p.G19S) alteration is located in exon 4 (coding exon 1) of the CAPN15 gene. This alteration results from a G to A substitution at nucleotide position 55, causing the glycine (G) at amino acid position 19 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
