Genes affected

KLF14 (HGNC:23025): (KLF transcription factor 14) This intronless gene encodes a member of the Kruppel-like family of transcription factors. The encoded protein functions as a transcriptional co-repressor, and is induced by transforming growth factor-beta (TGF-beta) to repress TGF-beta receptor II gene expression. This gene exhibits imprinted expression from the maternal allele in embryonic and extra-embryonic tissues. [provided by RefSeq, Jul 2013]

The c.437A>C (p.D146A) alteration is located in exon 1 (coding exon 1) of the KLF14 gene. This alteration results from a A to C substitution at nucleotide position 437, causing the aspartic acid (D) at amino acid position 146 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
