Genes affected

CABP2 (HGNC:1385): (calcium binding protein 2) This gene belongs to a subfamily of calcium binding proteins that share similarity to calmodulin. Like calmodulin, these family members can likely stimulate calmodulin-dependent kinase II and the protein phosphatase calcineurin. Calcium binding proteins are an important component of calcium mediated cellular signal transduction. Two transcript variants encoding different isoforms have been found for this gene.

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.016310334).

BS1

Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.000356 (520/1460976) while in subpopulation EAS AF= 0.0129 (514/39696). AF 95% confidence interval is 0.012. There are 9 homozygotes in gnomad4_exome. There are 250 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck. 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

Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. ClinVar contains an entry for this variant (Variation ID: 1329618). This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 183 of the CABP2 protein (p.Ala183Thr). This variant is present in population databases (rs117096937, gnomAD 0.09%). This variant has not been reported in the literature in individuals affected with CABP2-related conditions. -
