Tetratricopeptide repeat domain 8 (TTC8) also known as Bardet-Biedl syndrome 8 is a protein that in humans is encoded by the TTC8 gene.[1]

Function[edit]

TTC8 is associated with gamma-tubulin, BBS4, and PCM1 in the centrosome.[1] PCM1 in turn is involved in centriolar replication during ciliogenesis.[2]

TTC8 is located in the cilia of spermatids, retina, and bronchial epithelium cells.[1]

Clinical significance[edit]

Mutations in the TTC8 gene is one of 14 genes[3] identified as causal for Bardet-Biedl syndrome.[1][4]
