Genes affected

KLF2 (HGNC:6347): (KLF transcription factor 2) This gene encodes a protein that belongs to the Kruppel family of transcription factors. The encoded zinc finger protein is expressed early in mammalian development and is found in many different cell types. The protein acts to bind the CACCC box found in the promoter of target genes to activate their transcription. It plays a role in many processes during development and disease including adipogenesis, embryonic erythropoiesis, epithelial integrity, inflammation and t-cell viability.

The c.598C>T (p.P200S) alteration is located in exon 2 (coding exon 2) of the KLF2 gene. This alteration results from a C to T substitution at nucleotide position 598, causing the proline (P) at amino acid position 200 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
