OMIM : ⁵⁷ Microcephaly with or without chorioretinopathy, lymphedema, or mental retardation is an autosomal dominant disorder that involves an overlapping but variable spectrum of central nervous system and ocular developmental anomalies. Microcephaly ranges from mild to severe and is often associated with mild to moderate developmental delay and a characteristic facial phenotype with upslanting palpebral fissures, broad nose with rounded tip, long philtrum with thin upper lip, prominent chin, and prominent ears. Chorioretinopathy is the most common eye abnormality, but retinal folds, microphthalmia, and myopic and hypermetropic astigmatism have also been reported, and some individuals have no overt ocular phenotype. Congenital lymphedema, when present, is typically confined to the dorsa of the feet, and lymphoscintigraphy reveals the absence of radioactive isotope uptake from the webspaces between the toes (summary by Ostergaard et al., 2012). Robitaille et al. (2014) found that MCLMR includes a broader spectrum of ocular disease, including retinal detachment with avascularity of the peripheral retina, and noted phenotypic overlap with familial exudative vitreoretinopathy (FEVR; see EVR1, 133780). Birtel et al. (2017) observed intrafamilial and intraindividual variability in retinal phenotype, and noted that syndromic manifestations in some patients are too subtle to be detected during a routine ophthalmologic evaluation. Variable expressivity and reduced penetrance have also been observed in some families (Jones et al., 2014; Li et al., 2016). Autosomal recessive forms of microcephaly with chorioretinopathy have been reported (see 251270). See also Mirhosseini-Holmes-Walton syndrome (autosomal recessive microcephaly with pigmentary retinopathy and mental retardation; 268050), which has been mapped to chromosome 8q21.3-q22.1. (152950)

MalaCards based summary : Microcephaly with or Without Chorioretinopathy, Lymphedema, or Mental Retardation, also known as lymphedema, microcephaly and chorioretinopathy syndrome, is related to microcephaly and chorioretinopathy, autosomal recessive, 1 and exudative vitreoretinopathy 1. An important gene associated with Microcephaly with or Without Chorioretinopathy, Lymphedema, or Mental Retardation is KIF11 (Kinesin Family Member 11), and among its related pathways/superpathways are MHC class II antigen presentation and Long-term depression. Affiliated tissues include eye, retina and skin, and related phenotypes are ptosis and nystagmus

Disease Ontology : ¹² A syndrome characterized byvariable expression of microcephaly, ocular disorders including chorioretinopathy, congenital lymphedema of the lower limbs, and mild to moderate intellectual disability.
