Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 03, 2023The c.233C>T (p.A78V) alteration is located in exon 1 (coding exon 1) of the TEKT4 gene. This alteration results from a C to T substitution at nucleotide position 233, causing the alanine (A) at amino acid position 78 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
