Discovery of a TEKTIN-t/TEKT2 Gene Variant Encoding Sperm Flagellar Protein in Japanese Males [PDF]
テクチンは、ダイニンとともに精子の鞭毛や繊毛の形成に関与したタンパク質である。テクチンには、ヒトにおいて少なくとも6種類の遺伝子の存在が報告されている。テクチン遺伝子のうち、Tektin-t/Tekt2、Tekt3、もしくは Tekt4 が欠失することによって、精子の鞭毛が機能不全を起こし、なかでも Tektin-t/Tekt2 遺伝子の欠失は、雄性不妊症になることがマウスで示されている。男性不妊症の原因にテクチン遺伝子の機能不全が関与することが予想される。私たちは、ヒト TETIN-t/TEKT2

Only when a patient presents a situation of azoospermia with normal hormonal assays the attention is focussed on the epididymis and in all other cases testicular damage is automatically suspected. However, there are many instances where oligospermia cannot be explained and where the testicular biopsy shows vigourous spermatogenesis.

Screening of ′Y′ chromosome microdeletions in Iranian infertile males
Background : It has been hypothesized that microdeletions of Yq may account for a significant proportion of men with infertility. Three nonoverlapping regions, referred to as "azoospermia factors" (AZFa, b, c from proximal to distal Yq) have been defined
