Agrawal, from Boston Children&#8217;s Hospital, published in the <a href=\"https:\/\/www.cell.com\/ajhg\/fulltext\/S0002-9297(21)00227-5\"><em>American Journal of Human Genetics<\/em><\/a>. In this study, they have identified mutations in the <em>CLCN3<\/em> gene, which codes for a chloride transporter in endosomes, in eleven patients with different degrees of impairment in brain development. The results show that some of the mutations that affect a single chromosome copy cause a functional gain. However, one patient showed two mutations that lead to a loss of function. Therefore, both the gain and loss of function of the ClC-3 transporter have consequences on the development of the brain.<\/p>\n<p>On the other hand, Ra\u00fal Estevez and Alfons Macaya, from Vall d&#8217;Hebron, have led a study published in the journal <a href=\"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/humu.24252\"><em>Human Mutation<\/em><\/a> that has identified mutations in patients with brain development problems in the <em>CHRM1<\/em> gene, which codes for the muscarinic receptor M1, a receptor on the surface of neurons. Researchers have observed that mutations in this receptor make the protein unstable, leading to reduced signaling.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><em>The Bellvitge Biomedical Research Institute (IDIBELL) is a biomedical research center created in 2004.
