Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 08, 2024The c.274A>T (p.T92S) alteration is located in exon 3 (coding exon 2) of the TC2N gene. This alteration results from a A to T substitution at nucleotide position 274, causing the threonine (T) at amino acid position 92 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
