Introduction: McCune-Albright Syndrome (MAS) is a rare congenital disorder caused by post-zygotic activating mutations in GNAS gene. Due to the mosaic pattern of this disease, mutation abundance is frequently low in several tissues, including blood cells. The emergence of next-generation sequencing (NGS) methodologies has allowed the analysis of millions of DNA fragments simultaneously and independently, enabling detection of low mutation abundance. Aim: To es...
