A homozygous 80-kb deletion involving part of DNAJC6 and leptin receptor (LEPR) genes was also identified in a 7-year-old boy with dysmorphic features, obesity, epilepsy (febrile seizures from 6 months of age, tonic–clonic seizures from 2.5 years of age, and CSWS from 5 years of age) and ID, but no signs of Parkinsonism, possibly depending on the patient’s age [122]. This evidence concerns the gene LEPR and obesity due to melanocortin 4 receptor deficiency.
