Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 03, 2021The c.647G>T (p.R216L) alteration is located in exon 3 (coding exon 2) of the NTNG2 gene. This alteration results from a G to T substitution at nucleotide position 647, causing the arginine (R) at amino acid position 216 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
