The c.112C>G (p.P38A) alteration is located in exon 2 (coding exon 2) of the AVL9 gene. This alteration results from a C to G substitution at nucleotide position 112, causing the proline (P) at amino acid position 38 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
