This disease is associated with a defect in the synthesis of carbohydrates and their precursors, leading to the accumulation of unidentified uncomplicated oligomers and useless glycoproteins in cells. TMEM165-CDG is an autosomal recessive disease and is characterized by multiple clinical manifestations, including neurological and rare systemic disorders. These disorders can range from mild to severe, and their symptoms can include growth failure, cardiovascular pathologies, as well as liver and kidney pathologies.<\/p>\n<div id=\"ez-toc-container\"

of the disease and interesting historical facts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>TMEM165-CDG was initially described in 2014, when a group of researchers identified mutations in the TMEM165 gene in several patients exhibiting symptoms typical of glycosyltransferase syndromes. In this context, an important development was the creation of an international network of researchers and specialists working on this pathology, which allowed for the collection of more data on various aspects of the disease. One of the significant achievements was the establishment of a correlation between the types of mutations in the gene and the clinical manifestations of the disease. Thus, some mutations led to more severe manifestations than others, which made it possible to identify potential predictors of the course of the disease and its outcome.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%AD%D0%BF%D0%B8%D0%B4%D0%B5%D0%BC%D0%B8%D0%BE%D0%BB%D0%BE%D0%B3%D0%B8%D1%8F\"><\/span>Epidemiology<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>TMEM165-CDG is an extremely rare disease, making it difficult to estimate its prevalence and risk factors. The incidence rate is reported to be approximately 1 in 1,000,000 live births, but this number may vary depending on the population structure. Higher rates are observed in populations with a higher inbreeding load, where cases of TMEM165-CDG are more common. As of 2023, only a few dozen cases of the disease have been reported in the scientific literature, confirming its rarity.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%93%D0%B5%D0%BD%D0%B5%D1%82%D0%B8%D1%87%D0%B5%D1%81%D0%BA%D0%B0%D1%8F_%D0%BF%D1%80%D0%B5%D0%B4%D1%80%D0%B0%D1%81%D0%BF%D0%BE%D0%BB%D0%BE%D0%B6%D0%B5%D0%BD%D0%BD%D0%BE%D1%81%D1%82%D1%8C_%D0%BA_%D0%B4%D0%B0%D0%BD%D0%BD%D0%BE%D0%BC%D1%83_%D0%B7%D0%B0%D0%B1%D0%BE%D0%BB%D0%B5%D0%B2%D0%B0%D0%BD%D0%B8%D1%8E\"><\/span>Genetic predisposition to this disease<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>TMEM165-CDG is caused by mutations in the TMEM165 gene located on chromosome 2. In most cases, the disease is inherited in an autosomal recessive manner, meaning that two mutant alleles are required to cause clinical symptoms. Given the high level of homozygosity in some populations, key mutations have been identified, such as deletions and nucleotide substitutions, which result in complete loss of gene function. Such mutations have a major impact on glycoprotein biosynthesis and, as a consequence, cause clinical manifestations of the disease.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%A4%D0%B0%D0%BA%D1%82%D0%BE%D1%80%D1%8B_%D1%80%D0%B8%D1%81%D0%BA%D0%B0_%D0%B2%D0%BE%D0%B7%D0%BD%D0%B8%D0%BA%D0%BD%D0%BE%D0%B2%D0%B5%D0%BD%D0%B8%D1%8F_%D0%B4%D0%B0%D0%BD%D0%BD%D0%BE%D0%B3%D0%BE_%D0%B7%D0%B0%D0%B1%D0%BE%D0%BB%D0%B5%D0%B2%D0%B0%D0%BD%D0%B8%D1%8F\"><\/span>Risk factors for the development of this disease<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Risk factors for TMEM165-CDG are mainly related to genetic predisposition, as the disease is inherited in an autosomal recessive manner.
