The c.2407C>T (p.H803Y) alteration is located in exon 3 (coding exon 3) of the SYDE2 gene. This alteration results from a C to T substitution at nucleotide position 2407, causing the histidine (H) at amino acid position 803 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
