The c.3034C>G (p.P1012A) alteration is located in exon 22 (coding exon 22) of the SRGAP3 gene. This alteration results from a C to G substitution at nucleotide position 3034, causing the proline (P) at amino acid position 1012 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
