Collection Method: clinical testing

The c.820G>A (p.A274T) alteration is located in exon 1 (coding exon 1) of the ASPHD1 gene. This alteration results from a G to A substitution at nucleotide position 820, causing the alanine (A) at amino acid position 274 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
