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 GeneticsMar 01, 2024The c.519A>T (p.K173N) alteration is located in exon 6 (coding exon 4) of the GKAP1 gene. This alteration results from a A to T substitution at nucleotide position 519, causing the lysine (K) at amino acid position 173 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
