Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 27, 2023 | The c.74G>A (p.R25Q) alteration is located in exon 2 (coding exon 2) of the PKN3 gene. This alteration results from a G to A substitution at nucleotide position 74, causing the arginine (R) at amino acid position 25 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
