The c.1715A>G (p.Y572C) alteration is located in exon 7 (coding exon 7) of the SCFD2 gene. This alteration results from a A to G substitution at nucleotide position 1715, causing the tyrosine (Y) at amino acid position 572 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
