Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 08, 2022The c.200C>T (p.P67L) alteration is located in exon 3 (coding exon 2) of the TC2N gene. This alteration results from a C to T substitution at nucleotide position 200, causing the proline (P) at amino acid position 67 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
