Genes affected

AKAP7 (HGNC:377): (A-kinase anchoring protein 7) This gene encodes a member of the A-kinase anchoring protein (AKAP) family, a group of functionally related proteins that bind to a regulatory subunit (RII) of cAMP-dependent protein kinase A (PKA) and target the enzyme to specific subcellular compartments. AKAPs have a common RII-binding domain, but contain different targeting motifs responsible for directing PKA to distinct intracellular locations. Three alternatively spliced transcript variants encoding different isoforms have been described.[provided by RefSeq, Apr 2011]

The c.772T>A (p.Y258N) alteration is located in exon 7 (coding exon 7) of the AKAP7 gene. This alteration results from a T to A substitution at nucleotide position 772, causing the tyrosine (Y) at amino acid position 258 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
