Feb 23, 2023

The c.518C>A (p.A173E) alteration is located in exon 3 (coding exon 3) of the HEPHL1 gene. This alteration results from a C to A substitution at nucleotide position 518, causing the alanine (A) at amino acid position 173 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
