Collection Method: clinical testing

The c.617G>T (p.G206V) alteration is located in exon 7 (coding exon 7) of the CERS6 gene. This alteration results from a G to T substitution at nucleotide position 617, causing the glycine (G) at amino acid position 206 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
