The African American CRC patient study showed somatic mutations in genes APC, KRAS, Fc Receptor Like 5 (FCRL5), obscurin, cytoskeletal calmodulin and titin-interacting RhoGEF (OBSCN), Retinitis Pigmentosa 1 Like 1 (RP1L1), Dynein Axonemal Heavy Chain 17 (DNAH17), Zinc Finger Protein 568 (ZNF568), and Calcium Voltage-Gated Channel Subunit Alpha1 C (CACNA1C) [22]. This evidence concerns the gene RP1L1 and colorectal carcinoma.
