Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 07, 2022The c.788C>T (p.T263M) alteration is located in exon 6 (coding exon 4) of the TEKT3 gene. This alteration results from a C to T substitution at nucleotide position 788, causing the threonine (T) at amino acid position 263 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
