Ambry Genetics

Oct 04, 2022

The c.54C>G (p.C18W) alteration is located in exon 3 (coding exon 1) of the HSDL1 gene. This alteration results from a C to G substitution at nucleotide position 54, causing the cysteine (C) at amino acid position 18 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
