The c.842A>C (p.K281T) alteration is located in exon 3 (coding exon 3) of the SYT10 gene. This alteration results from a A to C substitution at nucleotide position 842, causing the lysine (K) at amino acid position 281 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
