The c.3589C>A (p.P1197T) alteration is located in exon 2 (coding exon 1) of the DSEL gene. This alteration results from a C to A substitution at nucleotide position 3589, causing the proline (P) at amino acid position 1197 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
