We report a case of Birt-Hogg-Dube syndrome (BHDS), a rare hereditary syndrome, the main visible sign of which is the development of multiple skin fibrofolliculomas. In our case, there was a manifestation of BHDS consisting in the absence of fibrofolliculomas and presence of other characteristic features of this syndrome: lung cysts and renal cancer. The 26-year-old woman was admitted to a clinic for diagnosis and treatment of a neoplasm of the left kidney and had a history of renal cell cancer (RCC) of the right kidney and spontaneous pneumothorax. Multiple tumors of the left kidney and lung cysts were observed upon clinical and laboratory testing. Tumors of the left kidney were resected and diagnosed by a pathologist as chromophobe RCC. Sequencing of <i>FLCN</i> exons 4–14 from blood DNA revealed the heterozygous germline nonsense mutation c.1429C&#x3e;T (p.R477*), confirming the diagnosis of BHDS. Several somatic variants were detected by tumor DNA sequencing using the Comprehensive Cancer Panel and Ion S5 platform. Medical-genetic counseling was conducted, and follow-up management was outlined. To our knowledge, this case report is the first comprehensive clinical and genetic examination of a patient with BHDS in Russia. The p.R477* mutation has been described by other authors in patients with fibrofolliculomas and lung cysts, but not in those with RCC, while RCC was the first manifestation of BHDS in our case. The case report may help geneticists, oncologists, and other specialists to better understand the clinical and genetic heterogeneity of BHDS in various populations.

Синдром Барде-Бидля - аутосомно-рецессивное заболевание, характеризующееся ожирением, пигментной дегенерацией сетчатки, полидактилией, задержкой психоречевого развития и структурными повреждениями почек. В работе представлены результаты применения МПС-панели, включающей кодирующие последовательности и прилегающие интронные области 21 гена, ассоциированного с синдромом Барде-Бидля. Впервые была проведена молекулярно-генетическая диагностика в группе из сорока российских пациентов с синдромом Барде-Бидля из неродственных семей. В результате исследования удалось подтвердить диагноз молекулярно-генетическим методом у 40% пациентов (n=16). В генах BBS1, BBS7 и BBS10 встретились повторяющиеся варианты. Частота встречаемости патогенных и вероятно патогенных вариантов в генах BBS1 и BBS10 у российских пациентов соответствует зарубежным данным. Варианты в гене BBS7 встретились у пяти человек, у четырех из них был обнаружен патогенный вариант c.1967_1968delTAinsC, не встречающийся в других популяциях. Результаты, представленные в статье, показывают значительный вклад в заболеваемость синдромом Барде-Бидля в российской популяции патогенных вариантов в гене BBS7. Bardet-Biedl syndrome is an autosomal recessive disorder characterized by obesity, retinitis pigmentosa, polydactyly, development delay, and structural kidney defects. This study shows the results of using an MPS panel that includes coding sequences and intronic areas of 21 genes associated with Bardet-Biedl syndrome. For the first time molecular genetic testing has been provided for the group of 40 Russian patiens with Bardet-Biedl syndrome from unrelated families. As a result of the testing, diagnoses were confirmed for 40% of the patients (n=16). The genes BBS1, BBS7, BBS10 had recurrent variants. The frequency of pathogenic and likely pathogenic variants in the genes BBS1 and BBS10 among Russian patients matches the research data in other countries. Variants in the BBS7 gene were found for five people, four of them had a pathogenic variant c.1967_1968delTAinsC, which is not present among other populations. Results provided in this article show the significant role of pathogenic variants in the BBS7 gene in patients with Bardet-Biedl syndrome in Russian population.

The thyroid gland is a rare site of clinically detectable tumor metastasis and kidneys are frequently the site of the parent malignancy. In the present review on thyroid metastases from renal cell carcinoma, cases were searched on PubMed by entering the strings: “renal carcinoma [or“hypernephroma”] AND thyroid metastasis/metastases”. Thus, we retrieved a total of 111 cases that were published between 1964 and 2007, a total that became 113 by adding two patients observed by us. The female to male ratio was 1.35:1. The primary renal cancer was almost always unilateral (90%) (with no significant side preference) and only rarely bilateral (9% in men, 4% in women), whereas bilaterality of thyroid metastases was relatively more frequent (28%). Thyroid metastasis from renal cancer was commonly single with a unique node that appears solid and hypoechoic at ultrasonography, approximately 9 years after nephrectomy. Concordance of lateralization was insignificantly greater for the right kidney/right thyroid lobe pattern (54%) than for the left kidney/left thyroid lobe pattern (40%), regardless of gender. Finally, survival was longer for women. Thyroid metastases, even if rare in the clinical practice, must be considered in the differential diagnosis of a thyroid nodule, particularly in patients who have a history of malignancies.

Modern Medical Practice

Summary Molecular genetic testing is part of modern medical practice. DNA tests are an essential part of diagnostics and genetic counseling in single gene diseases, while their application in polygenic disorders is still limited. Pharmacogenetics studies DNA variants associated with variations in drug efficacy and toxicity, and tests in this field are being developed rapidly. The main method for molecular genetic testing is the polymerase chain reaction, with a number of modifications. New methods, such as next generation sequencing and DNA microarray, should allow simultaneous analysis of a number of genes, even whole genome sequencing. Ethical concerns in molecular genetic testing are very important, along with legislation. After molecular genetic testing, interpretation of results and genetic counseling should be done by professionals. With the example of thrombophilia, we discuss questions about genetic testing, its possibilities and promises.
