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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 08, 2023The c.655C>T (p.R219C) alteration is located in exon 5 (coding exon 5) of the MFGE8 gene. This alteration results from a C to T substitution at nucleotide position 655, causing the arginine (R) at amino acid position 219 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
