Collection Method: clinical testing

The c.544G>A (p.E182K) alteration is located in exon 6 (coding exon 5) of the FAXDC2 gene. This alteration results from a G to A substitution at nucleotide position 544, causing the glutamic acid (E) at amino acid position 182 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
