However, we need to note here, in brain scRNA-seq, numerous ciliary genes, such as IFT (intraflagellar transport required for cilia formation) and BBS (Bardet Biedl Syndrome), exhibit exclusive expressions in neurons, but the large number of genes (8497 in total) expressed in neurons resulted in insufficiently specific results to warrant further analysis (Supplementary Figure S6; visit https://ciliogenics.com/). The gene discussed is BBS2; the disease is Bardet-Biedl syndrome.
