Collection Method: clinical testing

The c.625C>T (p.R209W) alteration is located in exon 7 (coding exon 6) of the ACCS gene. This alteration results from a C to T substitution at nucleotide position 625, causing the arginine (R) at amino acid position 209 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
