The c.836A>G (p.N279S) alteration is located in exon 9 (coding exon 9) of the GRAMD1A gene. This alteration results from a A to G substitution at nucleotide position 836, causing the asparagine (N) at amino acid position 279 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
