The c.1955A>C (p.D652A) alteration is located in exon 13 (coding exon 13) of the DCST2 gene. This alteration results from a A to C substitution at nucleotide position 1955, causing the aspartic acid (D) at amino acid position 652 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
