Abstract
Pituitary-dependent excess of GH may be a genetic disease, the literature describes a number of mutations that lead to an isolated excess of growth hormone, or as a symptom in a syndromic disease. The goal is to conduct a genome-wide search for associations of the patients with acromegaly genome to identify known mutations in the genes associated with this disease in adjacent sites. Create the first reference genomic base of Ukrainian patients with acromegaly to further study the causes of this disease and the introduction of personalized treatment in accordance with the genetic profile. Results. This article presents the results of a genome-wide search of the genome of 5 patients with acromegaly. The genotyping panel we used allowed us to identify 154 single-nucleotide polymorphisms in the genes that were previously described as associated with acromegaly. One patient is heterozygous for the alternative allele (AG) of SNPs rs33927012 of SDHB gene. This alternative allele is extremely rare in the world population (0.9%, in the European population — 2%). It is described as harmful by two analytical systems. Mutations in the SDHB gene lead to structural changes in the SDH protein (succinyl-dependent dehydrogenase), which plays a key role in the Krebs cycle and oxidative phosphorylation. This gene is a tumor suppressor gene and its mutations cause 3P syndrome (acromegaly, heochromocytoma, paraganglioma). We also found mutations in the genes SDHC, CDKN1B unique to some patients from this sample. Conclusion. Three exon threatening and potentially harmful mutations were found in the genes CDKN1B and SHDB, which are detected in patients with endocrine syndromes
