Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 16, 2022The c.1369A>G (p.I457V) alteration is located in exon 12 (coding exon 11) of the TC2N gene. This alteration results from a A to G substitution at nucleotide position 1369, causing the isoleucine (I) at amino acid position 457 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
