Genes affected

PEBP4 (HGNC:28319): (phosphatidylethanolamine binding protein 4) The phosphatidylethanolamine (PE)-binding proteins, including PEBP4, are an evolutionarily conserved family of proteins with pivotal biologic functions, such as lipid binding and inhibition of serine proteases (Wang et al., 2004 [PubMed 15302887]).[supplied by OMIM, Dec 2008]

The c.509A>G (p.K170R) alteration is located in exon 6 (coding exon 5) of the PEBP4 gene. This alteration results from a A to G substitution at nucleotide position 509, causing the lysine (K) at amino acid position 170 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
