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.

Jul 12, 2023

The c.302C>T (p.P101L) alteration is located in exon 4 (coding exon 3) of the IQCK gene. This alteration results from a C to T substitution at nucleotide position 302, causing the proline (P) at amino acid position 101 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
