not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2021The c.3071C>A (p.P1024Q) alteration is located in exon 16 (coding exon 16) of the PCNX2 gene. This alteration results from a C to A substitution at nucleotide position 3071, causing the proline (P) at amino acid position 1024 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
