The c.920A>G (p.Y307C) alteration is located in exon 8 (coding exon 7) of the FSTL5 gene. This alteration results from a A to G substitution at nucleotide position 920, causing the tyrosine (Y) at amino acid position 307 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
