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]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.12001526).

The c.985G>A (p.E329K) alteration is located in exon 13 (coding exon 13) of the GRIPAP1 gene. This alteration results from a G to A substitution at nucleotide position 985, causing the glutamic acid (E) at amino acid position 329 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
