Genes affected

GKAP1 (HGNC:17496): (G kinase anchoring protein 1) This gene encodes a protein that is highly similar to the mouse cGMP-dependent protein kinase anchoring protein 42kDa. The mouse protein has been found to localize with the Golgi and recruit cGMP-dependent protein kinase I alpha to the Golgi in mouse testes. It is thought to play a role in germ cell development. Transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2008]

Ambry Genetics

Jun 24, 2022

The c.25G>C (p.V9L) alteration is located in exon 3 (coding exon 1) of the GKAP1 gene. This alteration results from a G to C substitution at nucleotide position 25, causing the valine (V) at amino acid position 9 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
