CAKUT v1.58 CEP55 Rebecca Foulger Classified gene: CEP55 as Green List (high evidence)
CAKUT v1.58 CEP55 Rebecca Foulger Added comment: Comment on list classification: Updated rating from Grey to Green. Gene was added to the panel and rated Green by Zornitza Stark. 3 separate variants from 3 different ethnic groups (2 of the variants are likely Founder variants), plus zebrafish model. Most homozygous nonsense variants are embryonic lethal but PMID:28295209 report viable compound het missense variants.
CAKUT v1.58 CEP55 Rebecca Foulger Gene: cep55 has been classified as Green List (High Evidence).
CAKUT v1.57 CEP55 Rebecca Foulger Phenotypes for gene: CEP55 were changed from Multinucleated neurons, anhydramnios, renal dysplasia, cerebellar hypoplasia, and hydranencephaly, 236500 to Multinucleated neurons, anhydramnios, renal dysplasia, cerebellar hypoplasia, and hydranencephaly, 236500; MARCH syndrome; Meckel-like syndrome; lethal CEP55-related syndromes
CAKUT v1.56 CEP55 Rebecca Foulger Publications for gene: CEP55 were set to 30622327; 28264986
CAKUT v1.55 CEP55 Rebecca Foulger commented on gene: CEP55: PMID:32100459 (Barrie et al., 2020) describe 7 individuals from 5 families with biallelic CEP55 variants. This is the first reported case of missense variants in CEP55 (Previously only a prenatal lethal phenotype was reported due to homozygous CEP55 nonsense variants). The authors suggest that compound het cases with nonsense and missense CEP55 variants have a different viable phenotype. Homozgyosity for a splice variant in CEP55 is compatible with life. Renal abnormality was reported in Patient 3.
CAKUT v1.55 CEP55 Rebecca Foulger commented on gene: CEP55: PMID:28295209. Bondeson et al report a Swedish couple with 2 affected male fetuses homozygous for CEP55 p.Arg86*. Although the phenotype differed between fetuses, both exhibited kidney phenotypes (including renal dysplaisa). Segregation analysis supported the gene:disease association, and Haplotype analysis suggested a founder effect.

CAKUT v1.54 CEP55 Rebecca Foulger commented on gene: CEP55: PMID:28264986: Frosk et al, 2017 report a Dutch-German Mennonite family with 3 affected fetuses homozygous for CEP55 nonsense variant p.Ser425* presenting with MIM:236500 including renal dysplasia.

CAKUT v1.54 CEP55 Rebecca Foulger Phenotypes for gene: CEP55 were changed from Multinucleated neurons, anhydramnios, renal dysplasia, cerebellar hypoplasia, and hydranencephaly, MIM# 236500 to Multinucleated neurons, anhydramnios, renal dysplasia, cerebellar hypoplasia, and hydranencephaly, 236500
