Genes affected

TEKT1 (HGNC:15534): (tektin 1) 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 predominantly expressed in the testis and in mouse, tektin 1 mRNA was localized to the spermatocytes and round spermatids in the seminiferous tubules, indicating that it may play a role in spermatogenesis.

The c.1174C>A (p.Q392K) alteration is located in exon 8 (coding exon 7) of the TEKT1 gene. This alteration results from a C to A substitution at nucleotide position 1174, causing the glutamine (Q) at amino acid position 392 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
