Collection Method: clinical testing

The c.140C>T (p.T47M) alteration is located in exon 2 (coding exon 2) of the PHAX gene. This alteration results from a C to T substitution at nucleotide position 140, causing the threonine (T) at amino acid position 47 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
