Genes affected

KLF4 (HGNC:6348): (KLF transcription factor 4) This gene encodes a protein that belongs to the Kruppel family of transcription factors. The encoded zinc finger protein is required for normal development of the barrier function of skin. The encoded protein is thought to control the G1-to-S transition of the cell cycle following DNA damage by mediating the tumor suppressor gene p53. Mice lacking this gene have a normal appearance but lose weight rapidly, and die shortly after birth due to fluid evaporation resulting from compromised epidermal barrier function. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Sep 2015]

Ambry Genetics

Dec 26, 2023

The c.1123A>G (p.M375V) alteration is located in exon 4 (coding exon 4) of the KLF4 gene. This alteration results from a A to G substitution at nucleotide position 1123, causing the methionine (M) at amino acid position 375 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
