Ambry Genetics

Aug 16, 2021

The c.204C>G (p.N68K) alteration is located in exon 2 (coding exon 2) of the HEPHL1 gene. This alteration results from a C to G substitution at nucleotide position 204, causing the asparagine (N) at amino acid position 68 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
