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]

Collection Method: clinical testing

The c.365G>C (p.S122T) alteration is located in exon 4 (coding exon 3) of the TEKT2 gene. This alteration results from a G to C substitution at nucleotide position 365, causing the serine (S) at amino acid position 122 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
