Retinitis pigmentosa-type 28 (RP28) is the consequence of bi-allelic null mutations in the FAM161A gene (Bandah-Rozenfeld et al, 2010; Langmann et al, 2010), which codes for a protein (FAM161A) known to form part of the inner scaffold structure maintaining microtubule doublets of the connecting cilium and the basal body/centriole (Le Guennec et al, 2020). The gene discussed is FAM161A; the disease is retinitis pigmentosa.
