Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 05, 2022The c.790G>T (p.A264S) alteration is located in exon 6 (coding exon 4) of the TEKT3 gene. This alteration results from a G to T substitution at nucleotide position 790, causing the alanine (A) at amino acid position 264 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
