SPMIP6

Chr 9

sperm microtubule inner protein 6

Also known as: C9orf24, CBE1, NYD-SP22, SMRP1, bA573M23.4

The protein may participate in intramanchette transport and midpiece formation of the sperm tail and potentially functions in somatic cell proliferation. Mutations cause autosomal recessive primary ciliary dyskinesia with reduced generation of multiple motile cilia, leading to chronic respiratory infections, sinusitis, and potential fertility issues. This gene is highly constrained against loss-of-function variants, suggesting that biallelic mutations are required for disease manifestation.
