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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 22, 2024The c.1723G>A (p.A575T) alteration is located in exon 19 (coding exon 19) of the GRIPAP1 gene. This alteration results from a G to A substitution at nucleotide position 1723, causing the alanine (A) at amino acid position 575 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
