Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 13, 2023The c.409G>A (p.V137M) alteration is located in exon 3 (coding exon 2) of the NTNG2 gene. This alteration results from a G to A substitution at nucleotide position 409, causing the valine (V) at amino acid position 137 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
