Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 06, 2023The c.364C>G (p.P122A) alteration is located in exon 4 (coding exon 3) of the TC2N gene. This alteration results from a C to G substitution at nucleotide position 364, causing the proline (P) at amino acid position 122 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
