Genes affected

CFAP65 (HGNC:25325): (cilia and flagella associated protein 65) The protein encoded by this gene has putative coiled-coil domains and may be a transmembrane protein. The chicken ortholog of this gene is involved in the Rose-comb mutation, which is a large chromosome inversion, resulting in altered comb morphology and defects in sperm motility.

CFAP65 Gene-Disease associations (from GenCC):

• non-syndromic male infertility due to sperm motility disorder

  Inheritance: AR Classification: SUPPORTIVE Submitted by: Orphanet
• spermatogenic failure 40
