Genes affected

KLF7 (HGNC:6350): (KLF transcription factor 7) The protein encoded by this gene is a member of the Kruppel-like transcriptional regulator family. Members in this family regulate cell proliferation, differentiation and survival and contain three C2H2 zinc fingers at the C-terminus that mediate binding to GC-rich sites. This protein may contribute to the progression of type 2 diabetes by inhibiting insulin expression and secretion in pancreatic beta-cells and by deregulating adipocytokine secretion in adipocytes. A pseudogene of this gene is located on the long arm of chromosome 3. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2012]

The c.893T>C (p.M298T) alteration is located in exon 4 (coding exon 4) of the KLF7 gene. This alteration results from a T to C substitution at nucleotide position 893, causing the methionine (M) at amino acid position 298 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
