Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 06, 2024The c.1201G>T (p.D401Y) alteration is located in exon 8 (coding exon 6) of the TEKT3 gene. This alteration results from a G to T substitution at nucleotide position 1201, causing the aspartic acid (D) at amino acid position 401 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
