Collection Method: clinical testing

The c.553A>G (p.I185V) alteration is located in exon 4 (coding exon 3) of the PID1 gene. This alteration results from a A to G substitution at nucleotide position 553, causing the isoleucine (I) at amino acid position 185 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
