not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 11, 2022The c.116G>A (p.G39E) alteration is located in exon 2 (coding exon 1) of the CGN gene. This alteration results from a G to A substitution at nucleotide position 116, causing the glycine (G) at amino acid position 39 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
