Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 01, 2023The c.56G>A (p.R19H) 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 56, causing the arginine (R) at amino acid position 19 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
