Genes affected

MKI67 (HGNC:7107): (marker of proliferation Ki-67) Enables protein C-terminus binding activity. Involved in regulation of chromosome segregation and regulation of mitotic nuclear division. Located in chromosome; nuclear body; and nucleolus. Colocalizes with condensed chromosome. Implicated in Crohn's disease; breast cancer; human immunodeficiency virus infectious disease; and pancreatic cancer. Biomarker of several diseases, including Barrett's esophagus; autoimmune disease of musculoskeletal system (multiple); endocrine gland cancer (multiple); gastrointestinal system cancer (multiple); and interstitial cystitis.

The c.9421C>T (p.R3141W) alteration is located in exon 14 (coding exon 13) of the MKI67 gene. This alteration results from a C to T substitution at nucleotide position 9421, causing the arginine (R) at amino acid position 3141 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
