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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 02, 2023The c.734A>G (p.N245S) alteration is located in exon 8 (coding exon 6) of the GKAP1 gene. This alteration results from a A to G substitution at nucleotide position 734, causing the asparagine (N) at amino acid position 245 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
