The c.2978C>T (p.P993L) alteration is located in exon 6 (coding exon 6) of the SYDE2 gene. This alteration results from a C to T substitution at nucleotide position 2978, causing the proline (P) at amino acid position 993 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
