Collection Method: clinical testing

The c.445C>G (p.L149V) alteration is located in exon 5 (coding exon 4) of the ACCS gene. This alteration results from a C to G substitution at nucleotide position 445, causing the leucine (L) at amino acid position 149 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
