The c.2780C>A (p.A927D) alteration is located in exon 14 (coding exon 14) of the SRCIN1 gene. This alteration results from a C to A substitution at nucleotide position 2780, causing the alanine (A) at amino acid position 927 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
