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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 20, 2024The c.1580G>A (p.R527Q) alteration is located in exon 17 (coding exon 17) of the GRIPAP1 gene. This alteration results from a G to A substitution at nucleotide position 1580, causing the arginine (R) at amino acid position 527 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
