The c.128A>G (p.Y43C) alteration is located in exon 4 (coding exon 3) of the RERG gene. This alteration results from a A to G substitution at nucleotide position 128, causing the tyrosine (Y) at amino acid position 43 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
