The c.893G>C (p.G298A) alteration is located in exon 1 (coding exon 1) of the ASPHD1 gene. This alteration results from a G to C substitution at nucleotide position 893, causing the glycine (G) at amino acid position 298 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
