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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 16, 2023The c.433G>A (p.G145S) alteration is located in exon 4 (coding exon 3) of the TEKT1 gene. This alteration results from a G to A substitution at nucleotide position 433, causing the glycine (G) at amino acid position 145 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
