The c.953A>G (p.Y318C) alteration is located in exon 6 (coding exon 6) of the GDE1 gene. This alteration results from a A to G substitution at nucleotide position 953, causing the tyrosine (Y) at amino acid position 318 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
