The c.3215C>G (p.A1072G) alteration is located in exon 19 (coding exon 19) of the IGDCC4 gene. This alteration results from a C to G substitution at nucleotide position 3215, causing the alanine (A) at amino acid position 1072 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
