Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.55G>T (p.D19Y) alteration is located in exon 1 (coding exon 1) of the PHAX gene. This alteration results from a G to T substitution at nucleotide position 55, causing the aspartic acid (D) at amino acid position 19 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
