Thanks to new screening programs, we are now seeing an increase in Early Onset of ColoRectal Cancer (EOCRC) in patients below the age of 50 . Herein, we report a clinical case of a woman affected by EOCRC. This case illustrates the importance of genetic predisposition testing also in tumor patients. Indeed, for our patient, we used a combined approach of multiple molecular and cellular biology technologies that revealed the presence of an interesting novel variant in the SMARCA4 gene. The latter gene is implicated in damage repair processes and related, if mutated, to the onset of various tumor types. In addition, we stabilized Patient-Derived Organoids from the tumor tissue of the same patient and the result confirmed the presence of this novel pathogenic variant that has never been found before even in early onset cancer. In conclusion, with this clinical case, we want to underscore the importance of including patients even those below the age of 50 years in appropriate screening programs which should also include genetic tests for predisposition to early onset cancers.  \nKeywords: early cases of EOCRC; colon cancer; multi-gene oncology panel; NGS; SMARCA4 pathogenic mutation  \n1. Introduction  \nAmong the common malignancies, colorectal cancer (CRC) is the third leading cause of death in both men and women worldwide [1] . The incidence of CRC has increased in low-and middle-income countries throughout the past few decades, whereas its incidence has been steady in high-income countries [2] . Thanks to the implementation of screening programs that are progressively more registered in industrialized countries, it is becoming increasingly possible to detect colon cancer at early stages [3] .
