The c.662A>G (p.Y221C) alteration is located in exon 3 (coding exon 2) of the RBM4B gene. This alteration results from a A to G substitution at nucleotide position 662, causing the tyrosine (Y) at amino acid position 221 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
