Mutations in WDPCP have been associated with Bardet‐Biedl syndrome (BBS), characterised by retinitis pigmentosa, obesity, kidney dysfunction polydactyly and hypogonadism (Kim et al., 2010), most commonly caused by pituitary defects (Mujahid et al., 2018). Here, WDPCP is linked to obesity due to melanocortin 4 receptor deficiency.
