Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 26, 2024The c.265C>A (p.R89S) alteration is located in exon 1 (coding exon 1) of the TEKT4 gene. This alteration results from a C to A substitution at nucleotide position 265, causing the arginine (R) at amino acid position 89 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
