Mutational analysis of Aurora kinase C gene in Egyptian patients with macrozoospermia

Maha M. Kobesiy, Bardees M. Foda, Ola S.M. Ali, Ibrahim Fahmy, więcej

Macrozoospermia is a rare syndrome. The key marker of the disease is a high percentage of spermatozoa with abnormal phenotypes namely enlarged head and multiple tails. The presence of at least 70% of spermatozoa with a large head is usually associated with Aurora kinase C gene (AURKC) mutations. We sought to assess AURKC as a potential genetic actor of macrozoospermia in a sample of infertile Egyptian...
