Genes affected

GRIPAP1 (HGNC:18706): (GRIP1 associated protein 1) This gene encodes a guanine nucleotide exchange factor for the Ras family of small G proteins (RasGEF). The encoded protein interacts in a complex with glutamate receptor interacting protein 1 (GRIP1) and plays a role in the regulation of AMPA receptor function. [provided by RefSeq, Aug 2013]

Ambry Genetics

Nov 25, 2024

The c.1925G>A (p.R642H) alteration is located in exon 21 (coding exon 21) of the GRIPAP1 gene. This alteration results from a G to A substitution at nucleotide position 1925, causing the arginine (R) at amino acid position 642 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
