The "toe syndactyly, telecanthus and anogenital and renal malformations" (STAR) syndrome is a rare X-linked dominant inherited kidney ciliopathy caused by CCNQ gene mutations. Here, we investigated the genotype and phenotype in the first two twin sisters with a novel tail extension CCNQ variant in Asia. Genetic variants of the pedigree were screened using whole-exome sequence analysis and validated by direct Sanger sequencing.

Objective: This study aimed to investigate clinical, surgical, and genetic data of neonates with anorectal malformation (ARM).
Study Design: A retrospective observational study was conducted on neonates with ARM as an isolated type (group 1), with ≤2 (group 2), and with ≥3 associated malformations (group 3), born between 2009 and 2020. Distribution of ARM, associated abnormalities and genetic testing were analyzed, and risk factors for adverse outcomes were identified.

Purpose: To report multimodal imaging of novel retinal findings in a case of syndactyly, telecanthus, anogenital, and renal malformations (STAR) syndrome.
Observations: A 5-year old patient with STAR syndrome, an ultra-rare developmental disorder composed of syndactyly, telecanthus, anogenital, and renal malformations, was found to have bilateral macular yellow pigmentary changes and peripheral retinal pigment epithelial changes in a radial pattern highlighted by fundus autofluorescence (FAF) imaging. Optical coherence tomography (OCT) of the macula revealed foveal hypoplasia, ellipsoid zone disruption, and outer retinal atrophy suggestive of a retinal degeneration.

Background: CDK10 is a poorly known cyclin M (CycM)-dependent kinase. Loss-of-function mutations in the genes encoding CycM or CDK10 cause, respectively, STAR or Al Kaissi syndromes, which present a constellation of malformations and dysfunctions. Most reported mutations abolish gene expression, but two mutations found in 3' exons could allow the expression of CDK10 and CycM truncated variants.

The primary cilium is a key organelle in numerous physiological and developmental processes. Genetic defects in the formation of this non-motile structure, in its maintenance and function, underlie a wide array of ciliopathies in human, including craniofacial, brain and heart malformations, and retinal and hearing defects. We used exome sequencing to study the molecular basis of disease in an 11-year-old female patient who suffered from growth retardation, global developmental delay with absent speech acquisition, agenesis of corpus callosum and paucity of white matter, sensorineural deafness, retinitis pigmentosa, vertebral anomalies, patent ductus arteriosus, and facial dysmorphism reminiscent of STAR syndrome, a suspected ciliopathy.
