The c.771T>A (p.D257E) alteration is located in exon 3 (coding exon 3) of the SYT10 gene. This alteration results from a T to A substitution at nucleotide position 771, causing the aspartic acid (D) at amino acid position 257 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
