Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 13, 2023The c.703G>A (p.D235N) alteration is located in exon 1 (coding exon 1) of the NTN3 gene. This alteration results from a G to A substitution at nucleotide position 703, causing the aspartic acid (D) at amino acid position 235 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
