Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 17, 2024The c.178G>A (p.D60N) 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 178, causing the aspartic acid (D) at amino acid position 60 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
