The c.2969A>C (p.Q990P) alteration is located in exon 17 (coding exon 17) of the ABTB2 gene. This alteration results from a A to C substitution at nucleotide position 2969, causing the glutamine (Q) at amino acid position 990 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
