Collection Method:clinical testing

The c.1270C>T (p.R424W) alteration is located in exon 6 (coding exon 6) of the PAOX gene. This alteration results from a C to T substitution at nucleotide position 1270, causing the arginine (R) at amino acid position 424 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
