The c.3178G>T (p.V1060L) alteration is located in exon 22 (coding exon 22) of the SRGAP3 gene. This alteration results from a G to T substitution at nucleotide position 3178, causing the valine (V) at amino acid position 1060 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
