Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 21, 2023The c.398A>G (p.Y133C) alteration is located in exon 4 (coding exon 3) of the TC2N gene. This alteration results from a A to G substitution at nucleotide position 398, causing the tyrosine (Y) at amino acid position 133 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
