Centrioles are intriguing cylindrical organelles composed of triplet microtubules. Proteomic data suggest that a large number of proteins besides tubulin are necessary for the formation and maintenance of a centriole's complex structure. Expansion of the preexisting centriole proteome from the green alga Chlamydomonas reinhardtii revealed additional human disease genes, emphasizing the significance of centrioles in normal human tissue homeostasis. We found that two classes of ciliary disease genes were highly represented among the basal body proteome: cystic kidney disease (especially nephronophthisis) syndromes, including Meckel/Joubert-like and oral-facial-digital syndrome, caused by mutations in CEP290, MKS1, OFD1, and AHI1/Jouberin proteins and cone-rod dystrophy syndrome genes, including UNC-119/HRG4, NPHP4, and RPGR1. We further characterized proteome of the centriole (POC) 1, a highly abundant WD40 domain-containing centriole protein. We found that POC1 is recruited to nascent procentrioles and localizes in a highly asymmetrical pattern in mature centrioles corresponding to sites of basal-body fiber attachment. Knockdown of POC1 in human cells caused a reduction in centriole duplication, whereas overexpression caused the appearance of elongated centriole-like structures. Together, these data suggest that POC1 is involved in early steps of centriole duplication as well as in the later steps of centriole length control.

The oral-facial-digital syndrome belongs to a group of hereditary diseases, manifested by multiple birth defects (usually, the face and fingers). At the current stage, there are 14 genetic variations of the oral-facial-digital syndrome. The presence of various abnormalities of the oral cavity, face and fingers is common for all of them, but each syndrome has a specific phenotype or type of inheritance. The etiology of this syndrome is unknown. It is inherited in an X-linked dominant pattern. Aim of the study: to describe and analyze the clinical case of oral-facial-digital syndrome. Data of the patient (Kira M., 11 months old): clinical-anamnestic examination, chest radiography, ultrasound investigation, molecular-genetic testing OFD1. Results Numerous miliae are detected on the face and ears of the child. Facial dysmorphy (large wide eyes, epicantus, wide nose bridge, telecantus, small mouth, small beak shaped nose, hypoplasia of the wings of the nose, small chin). The large fontanel is closed. Focal alopecia and dry hair are noted. Syndactyly of 2nd-3rd toes, asymmetrical shortening of the index finger of the right hand. Oral cavity examination reveals cleft palate, ankyloglossy and tongue lobulation. Transcranial ultrasonography: M echodex = 50.0 mm. M echosin = 52.0 mm. VIII = 6.9 mm (N up to 3.0 mm). V latdex = 24.4 mm, V latsin = 25.0 mm (N up to 16.0 mm). Neurologist's consultation: "Congenital brain malformation: agenesis of corpus callosum, congenital cerebral cysts." Ultrasound examination of the abdominal organs detected liver enlargement (anteroposterior size of the right lobe: 78 mm (N up to 65 mm), left lobe: 0.38 mm (+1.5 cm) Conclusion Oral-facial-digital syndrome type I is an inherited pathology, which in most cases is diagnosed immediately after birth on the basis of oral, facial and digital anomalies. Molecular genetic study makes it possible to confirm this disease and provide counseling to family members. Elimination of some developmental defects (hard palate plastic, correction of frenulum hyperthrophy), as well as a properly selected complex of therapeutic and rehabilitation measures greatly improves the quality of life of the patient and contributes to a favorable forecast.
