Collection Method: clinical testing

The c.131C>A (p.S44Y) alteration is located in exon 3 (coding exon 3) of the PDXDC1 gene. This alteration results from a C to A substitution at nucleotide position 131, causing the serine (S) at amino acid position 44 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
