Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 29, 2023The c.1220C>T (p.P407L) alteration is located in exon 8 (coding exon 6) of the TEKT3 gene. This alteration results from a C to T substitution at nucleotide position 1220, causing the proline (P) at amino acid position 407 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
