The c.1492G>A (p.E498K) alteration is located in exon 18 (coding exon 18) of the SDAD1 gene. This alteration results from a G to A substitution at nucleotide position 1492, causing the glutamic acid (E) at amino acid position 498 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
