Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 05, 2024The c.353T>C (p.L118S) alteration is located in exon 1 (coding exon 1) of the TEKT4 gene. This alteration results from a T to C substitution at nucleotide position 353, causing the leucine (L) at amino acid position 118 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
