The c.3166C>A (p.P1056T) alteration is located in exon 22 (coding exon 22) of the SRGAP3 gene. This alteration results from a C to A substitution at nucleotide position 3166, causing the proline (P) at amino acid position 1056 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
