Collection Method: clinical testing

The c.1098G>T (p.R366S) alteration is located in exon 6 (coding exon 6) of the FAXC gene. This alteration results from a G to T substitution at nucleotide position 1098, causing the arginine (R) at amino acid position 366 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
