Yuan-Harel-Lupski syndrome is a complex neurodevelopmental disorder characterized by global developmental delay and early-onset peripheral neuropathy. The disorder comprises features of both demyelinating Charcot-Marie-Tooth disease type 1A (CMT1A ), which results from duplication of the PMP22 gene on 17p12, and Potocki-Lupski syndrome (PTLS ), which results from duplication of a slightly proximal region on 17p11.2 that includes the RAI1 gene. These 2 loci are about 2.5 Mb apart. The resultant YUHAL phenotype may be more severe in comparison to the individual contributions of each gene, with particularly early onset of peripheral neuropathy and features of both central and peripheral nervous system involvement (summary by Yuan et al., 2015).

Macrocephaly, dysmorphic facies, and psychomotor retardation (MDFPMR) is an autosomal recessive neurodevelopmental disorder characterized by large head and somatic overgrowth apparent at birth followed by global developmental delay. Affected individuals have characteristic dysmorphic facial features and persistently large head, but increased birth weight normalizes with age. Additional neurologic features, including seizures, hypotonia, and gait ataxia, may also occur. Patients show severe intellectual impairment (summary by Ortega-Recalde et al., 2015).

Al Kaissi syndrome is an autosomal recessive developmental disorder characterized by growth retardation, spine malformation, particularly of the cervical spine, dysmorphic facial features, and delayed psychomotor development with moderate to severe intellectual disability (summary by Windpassinger et al., 2017).

Autosomal recessive cutis laxa type IIC (ARCL2C) is characterized by generalized skin wrinkling with sparse subcutaneous fat and dysmorphic progeroid facial features. Most patients also exhibit severe hypotonia as well as cardiovascular involvement (summary by Van Damme et al., 2017).For a general phenotypic description and a discussion of genetic heterogeneity of autosomal recessive cutis laxa, see ARCL1A (OMIM ).

Gordon syndrome, also known as distal arthrogryposis type 3, is an extremely rare multiple congenital malformation syndrome characterized by congenital contractures of hand and feet with variable degrees of severity of camptodactyly, clubfoot and, less frequently, cleft palate. Intelligence is normal but in some cases, additional abnormalities, such as short stature, kyphoscoliosis, ptosis, micrognathia, and cryptorchidism may also be present. Gordon syndrome, Marden-Walker syndrome and arthrogryposis with oculomotor limitation and electroretinal anomalies clinically and genetically overlap, and could represent variable expressions of the same condition.
