Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2024The c.875C>T (p.T292M) alteration is located in exon 9 (coding exon 8) of the TC2N gene. This alteration results from a C to T substitution at nucleotide position 875, causing the threonine (T) at amino acid position 292 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
