Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 10, 2022The c.1454G>A (p.R485Q) alteration is located in exon 9 (coding exon 7) of the TEKT3 gene. This alteration results from a G to A substitution at nucleotide position 1454, causing the arginine (R) at amino acid position 485 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
