The c.791A>G (p.Y264C) alteration is located in exon 6 (coding exon 6) of the SPRED2 gene. This alteration results from a A to G substitution at nucleotide position 791, causing the tyrosine (Y) at amino acid position 264 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
