Somatic mutations of <em>PRKCE<\/em> have been described in tumors.<\/p>\n<p>Using whole-exome sequencing, researchers have now for the first time identified a de novo <em>PRKCE<\/em> mutation as the disease-causing genetic variant in a patient with SHORT syndrome. This is a very rare malformation syndrome manifesting mainly as a combination of short stature, lipoatrophy, and characteristic facial features (triangular face, broad forehead, deep-set eyes, low-hanging columella, small chin). To date, autosomal dominant mutations of the <em>PIK3R1<\/em> gene have been the only known genetic cause of SHORT syndrome, resulting in a dysregulation of the PI3K-AKT-mTOR signaling pathway. In their functional investigations of the newly identified <em>PRKCE<\/em> mutation, the scientists showed that it leads to a partial loss of function of the encoded protein kinase C-epsilon and affects AKT activation via compromised mTORC2 complex function. This novel genetic defect in SHORT syndrome thus triggers a mechanism that, similarly to the known disease-causing <em>PIK3R1<\/em> mutations, impairs AKT-mTOR activation.<\/p>\n<p>The results of this study have been published in <em>Human Molecular Genetics<\/em>.<\/p>\n[vc_column_text] Alcantara D, Elmslie F, Tetreault M, \u2026, O&#8217;Driscoll M.
