Genes affected

CKB (HGNC:1991): (creatine kinase B) The protein encoded by this gene is a cytoplasmic enzyme involved in energy homeostasis. The encoded protein reversibly catalyzes the transfer of phosphate between ATP and various phosphogens such as creatine phosphate. It acts as a homodimer in brain as well as in other tissues, and as a heterodimer with a similar muscle isozyme in heart. The encoded protein is a member of the ATP:guanido phosphotransferase protein family. A pseudogene of this gene has been characterized. [provided by RefSeq, Jul 2008]

May 01, 2024

The c.1082T>C (p.I361T) alteration is located in exon 8 (coding exon 7) of the CKB gene. This alteration results from a T to C substitution at nucleotide position 1082, causing the isoleucine (I) at amino acid position 361 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
