Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 17, 2021The c.547C>G (p.R183G) alteration is located in exon 3 (coding exon 2) of the NTNG2 gene. This alteration results from a C to G substitution at nucleotide position 547, causing the arginine (R) at amino acid position 183 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
