Collection Method: clinical testing

The c.1795G>A (p.G599R) alteration is located in exon 7 (coding exon 7) of the AGAP4 gene. This alteration results from a G to A substitution at nucleotide position 1795, causing the glycine (G) at amino acid position 599 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
