Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 14, 2023The c.449G>A (p.R150H) alteration is located in exon 1 (coding exon 1) of the TEKT4 gene. This alteration results from a G to A substitution at nucleotide position 449, causing the arginine (R) at amino acid position 150 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
