Ambry Genetics

Oct 27, 2022

The c.598C>G (p.L200V) alteration is located in exon 6 (coding exon 6) of the HACD4 gene. This alteration results from a C to G substitution at nucleotide position 598, causing the leucine (L) at amino acid position 200 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
