Hennekam lymphangiectasia-lymphedema syndrome is an autosomal recessive disorder characterized by generalized lymphatic dysplasia affecting various organs, including the intestinal tract, pericardium, and limbs. Additional features of the disorder include facial dysmorphism and cognitive impairment (summary by Alders et al., 2014).For a discussion of genetic heterogeneity of Hennekam lymphangiectasia-lymphedema syndrome, see HKLLS1 (OMIM ).

Syndromic microphthalmia, type 5 is characterized by the association of a range of ocular anomalies (anophthalmia, microphthalmia and retinal abnormalities) with variable developmental delay and central nervous system malformations.

Megalencephaly-polymicrogyria-postaxial polydactyly-hydrocephalus syndrome is characterized by megalencephaly, polymicrogyria, and hydrocephalus with variable polydactyly. It has been described in six unrelated patients. Intellectual deficit or slow development is also present. The mode of inheritance of this syndrome is unknown since all cases were sporadic.

Micro syndrome is an autosomal recessive disorder caracterised by ocular and neurodevelopmental defects and by microgenitalia. It presents with severe intellectual disability, microcephaly, congenital cataract, microcornea, microphthalmia, agenesis/hypoplasia of the corpus callosum, and hypogenitalism.

Warburg Micro syndrome is a rare autosomal recessive syndrome characterized by microcephaly, microphthalmia, microcornea, congenital cataracts, optic atrophy, cortical dysplasia, in particular corpus callosum hypoplasia, severe mental retardation, spastic diplegia, and hypogonadism (summary by Morris-Rosendahl et al., 2010). Genetic Heterogeneity of Warburg Micro SyndromeWarburg Micro syndrome-2 (WARBM2 ) is caused by mutation in the RAB3GAP2 gene (OMIM ) on chromosome 1q41. WARBM3 (OMIM ) is caused by mutation in the RAB18 gene (OMIM ) on chromosome 10p12. WARBM4 (OMIM ) is caused by mutation in the TBC1D20 gene (OMIM ) on chromosome 20p13.See also Martsolf syndrome (OMIM ), a clinically overlapping but milder autosomal recessive disorder caused by autosomal recessive mutation in the RAB3GAP2 gene.Handley et al. (2013) provided an overview of the disease variants identified in the RAB3GAP1, RAB3GAP2, and RAB18 genes, noting that a total of 144 families with WARBM and 9 families with Martsolf syndrome had been studied. Mutations were identified in RAB3GAP1 in 41% of cases, in RAB3GAP2 in 7% of cases, and in RAB18 in 5% of cases. Although RAB18 had not been linked to RAB3 pathways, Handley et al. (2013) stated that mutations in all 3 genes cause an indistinguishable phenotype, making it likely that there is some functional overlap.
