Genes affected
MFAP5 (HGNC:29673): (microfibril associated protein 5) This gene encodes a 25-kD microfibril-associated glycoprotein which is a component of microfibrils of the extracellular matrix. The encoded protein promotes attachment of cells to microfibrils via alpha-V-beta-3 integrin. Deficiency of this gene in mice results in neutropenia. Alternate splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2014]

Submissions by phenotype

Cardiovascular phenotype Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 20, 2024The c.444delT variant, located in coding exon 9 of the MFAP5 gene, results from a deletion of one nucleotide at nucleotide position 444, causing a translational frameshift with a predicted alternate stop codon (p.R149Gfs*28). This alteration is expected to result in protein truncation. However, loss of function of MFAP5 has not been established as a mechanism of disease. The evidence for this gene-disease relationship is limited; therefore, the clinical significance of this alteration is unclear. -
