Genes affected

MFGE8 (HGNC:7036): (milk fat globule EGF and factor V/VIII domain containing) This gene encodes a preproprotein that is proteolytically processed to form multiple protein products. The major encoded protein product, lactadherin, is a membrane glycoprotein that promotes phagocytosis of apoptotic cells. This protein has also been implicated in wound healing, autoimmune disease, and cancer. Lactadherin can be further processed to form a smaller cleavage product, medin, which comprises the major protein component of aortic medial amyloid (AMA). Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2015]

Dec 21, 2023

The c.1067A>T (p.N356I) alteration is located in exon 8 (coding exon 8) of the MFGE8 gene. This alteration results from a A to T substitution at nucleotide position 1067, causing the asparagine (N) at amino acid position 356 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
