The c.299C>T (p.A100V) alteration is located in exon 2 (coding exon 1) of the RNF220 gene. This alteration results from a C to T substitution at nucleotide position 299, causing the alanine (A) at amino acid position 100 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
