Genes affected
TEKT3 (HGNC:14293): (tektin 3) This gene product belongs to the tektin family of proteins. Tektins comprise a family of filament-forming proteins that are coassembled with tubulins to form ciliary and flagellar microtubules. The exact function of this gene is not known.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 05, 2023The c.1448C>G (p.T483S) alteration is located in exon 9 (coding exon 7) of the TEKT3 gene. This alteration results from a C to G substitution at nucleotide position 1448, causing the threonine (T) at amino acid position 483 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
