Genes affected

TEKT2 (HGNC:11725): (tektin 2) 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. This gene is expressed in the testis and its protein is localized to the flagella of the sperms, indicating that it may play a role in spermatogenesis. [provided by RefSeq, Jul 2008]

Ambry Genetics

Sep 29, 2023

The c.154C>G (p.Q52E) alteration is located in exon 2 (coding exon 1) of the TEKT2 gene. This alteration results from a C to G substitution at nucleotide position 154, causing the glutamine (Q) at amino acid position 52 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
