Lipodystrophy-intellectual disability-deafness syndrome is an extremely rare form of genetic lipodystrophy (see this term), reported in 3 patients from one family to date, characterized by generalized congenital lipodystrophy, low birth weight, progressive sensorineural deafness occurring in childhood, intellectual deficit, progressive osteopenia, delayed skeletal maturation, skeletal abnormalities described as slender, undermineralized tubular bones, and dense metaphyseal striations in the distal femur, ulna and radius of older patients. Autosomal recessive inheritance has been suggested.

Neurodevelopmental disorder with craniofacial dysmorphism and skeletal defects (NEDCDS) is characterized by global developmental delay, severely impaired intellectual development with poor or absent speech, characteristic facial features, and variable skeletal abnormalities. Additional features include feeding difficulties, inability to walk or walking with an abnormal gait, and cerebellar or other abnormalities on brain imaging (Reichert et al., 2020).
