Ambry Genetics

Dec 28, 2023

The c.56G>C (p.R19P) alteration is located in exon 1 (coding exon 1) of the PXMP4 gene. This alteration results from a G to C substitution at nucleotide position 56, causing the arginine (R) at amino acid position 19 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
