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]

Ambry Genetics

Dec 14, 2023

The c.233T>C (p.I78T) alteration is located in exon 3 (coding exon 2) of the PEBP4 gene. This alteration results from a T to C substitution at nucleotide position 233, causing the isoleucine (I) at amino acid position 78 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
