The c.361C>G (p.P121A) alteration is located in exon 2 (coding exon 2) of the ANKRD33 gene. This alteration results from a C to G substitution at nucleotide position 361, causing the proline (P) at amino acid position 121 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
