Zornitza Stark gene: CEP55 was added gene: CEP55 was added to Intellectual disability syndromic and non-syndromic. Sources: Literature Mode of inheritance for gene: CEP55 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: CEP55 were set to 32100459 Phenotypes for gene: CEP55 were set to Multinucleated neurons, anhydramnios, renal dysplasia, cerebellar hypoplasia, and hydranencephaly, MIM# 236500; Microcephaly; Intellectual disability Review for gene: CEP55 was set to GREEN Added comment: Homozygous nonsense variants in CEP55 are associated with a lethal condition characterized by multinucleated neurons, anhydramnios, renal dysplasia, cerebellar hypoplasia, and hydranencephaly (MARCH syndrome) also known as Meckel-like syndrome. New report of seven living individuals from five families with biallelic CEP55 variants. Four unrelated individuals with microcephaly, speech delays, and bilateral toe syndactyly all had a common CEP55 variant c.70G>A p.(Glu24Lys) in trans with nonsense variants. Three siblings were homozygous for a consensus splice site variant near the end of the gene. These affected girls all had severely delayed development, microcephaly, and varying degrees of lissencephaly/pachygyria. This series suggests that individuals with compound heterozygosity for nonsense and missense variants in CEP55 have a different viable phenotype. Sources: Literature |
