Family with sequence similarity 83, member A (FAM83A), also known as BJ-TSA-9, is located on chromosome 8q24 and was originally identified as a potential tumor-specific gene by a bioinformatics approach.15 Furthermore, FAM83A is overexpressed in multiple human tumors, including lung, breast, testis and bladder cancer,16, 17, 18 suggesting that FAM83A may have an oncogenic role during the development and progression of cancer. The gene discussed is SACK1A; the disease is urinary bladder carcinoma.
