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.451A>G (p.T151A) alteration is located in exon 2 (coding exon 2) of the KLF7 gene. This alteration results from a A to G substitution at nucleotide position 451, causing the threonine (T) at amino acid position 151 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
