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 06, 2023The c.1064C>T (p.A355V) alteration is located in exon 7 (coding exon 5) of the TEKT3 gene. This alteration results from a C to T substitution at nucleotide position 1064, causing the alanine (A) at amino acid position 355 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
