Genes affected

IQCK (HGNC:28556): (IQ motif containing K) This gene belongs to the IQ motif-containing family of proteins. The IQ motif serves as a binding site for different EF-hand proteins such as calmodulin. This gene was identified as a potential candidate gene for obsessive-compulsive disorder in a genome-wide association study. Alternative splicing of this gene results in multiple transcript variants.

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.56).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.253 is higher than 0.05.
