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.307G>A (p.A103T) alteration is located in exon 4 (coding exon 3) of the PEBP4 gene. This alteration results from a G to A substitution at nucleotide position 307, causing the alanine (A) at amino acid position 103 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
