BICRA and colorectal carcinoma: Among these mutations, an eight‐cytosine (C8) mononucleotide short tandem repeat in the sixth exon of the GLTSCR1 gene was identified as a novel microsatellite site, at which the indel mutation (C9/C7) resulted in a GLTSCR1 frameshift mutation in CRC samples (highlighted in Figure 1A and Table S1, Supporting Information).
