Overview

This report describes neurooculocardiogenitourinary syndrome (NOCGUS), which shows autosomal dominant inheritance. The human gene implicated in this disease is WDR37. There is a single high-ranking ortholog of WDR37 in Drosophila, Dmel\Wdr37. Some alleles have been generated, including an amorphic allele and RNAi targeting constructs.

The human gene Hsap\WDR37 has been introduced into flies, both as wild-type and as variants associated with NOCGUS, WDR37:p.Ser129Cys and WDR37:p.Thr125Ile .

In Drosophila, Wdr37-null flies are viable, but are bang-sensitive (a phenotype related to seizure sensitivity, see FBcv:0000391), have low grip strength, and have defective courtship behavior (inability of male to grip onto female). Expression of wild-tye Hsap\WDR37 provides heterologous rescue (functional complementation), but the two mutant forms do not.

Symptoms and phenotype

Five unrelated probands had eye anomalies (mostly bilateral colobomas), dysmorphic features, seizures, feeding difficulties, developmental delay, intellectual disability, and no verbal development; most of the probands had congenital cardiac defects and hypotonia. Brain imaging studies demonstrated several consistent abnormalities including mildly simplified gyral pattern with relatively shallow sulci, small and dysplastic hippocampi, mild to moderate reduced volume of white matter, mild ventriculomegaly, diffusely thin corpus callosum, mildly thin brainstem with small pons, and moderately diffuse cerebellar and vermis hypoplasia with a striking foliar dysplasia. (Adopted from Kanca et al. 2019, FBrf0243068.)

Neurooculocardiogenitourinary syndrome (NOCGUS) is a multisystem disorder characterized by poor growth and anomalies of the ocular, craniofacial, neurologic, cardiovascular, genitourinary, skeletal, and gastrointestinal systems. Lethality before 2 years of age has been observed (Reis et al. 2019, pubmed:31327510). [from MIM:618652, 2019.11.05]

Genetics

Of the combined nine probands identified by Kanca et al. 2019 (FBrf0243068) and Reis et al. 2019 (pubmed:31327510), all had de novo mutations in WDR37.

Between Kanca et al. 2019 (FBrf0243068) and Reis et al. 2019 (pubmed:31327510), nine unrelated, non-consanguineous probands showed heterozygosity for de novo missense mutations in the WDR37 gene. [from MIM:618652, 2019.11.05]

Cellular phenotype and pathology
Molecular information

The WDR37 gene contains an identifiable coiled coil region and seven WDRs (WD40 repeats), which are stretches of ∼40 amino acid repeats that often terminate in Trp or Asp . WDRs are suggested to form 8 bladed beta propeller folds that form protein interaction interfaces. (Adopted from Kanca et al. 2019, FBrf0243068.)
