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

not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJun 10, 2022Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This variant has not been reported in the literature in individuals affected with MFAP5-related conditions. This variant is present in population databases (rs765205871, gnomAD 0.05%), and has an allele count higher than expected for a pathogenic variant. This sequence change replaces arginine, which is basic and polar, with serine, which is neutral and polar, at codon 152 of the MFAP5 protein (p.Arg152Ser). -
Cardiovascular phenotype Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 09, 2022The p.R152S variant (also known as c.454C>A), located in coding exon 9 of the MFAP5 gene, results from a C to A substitution at nucleotide position 454. The arginine at codon 152 is replaced by serine, an amino acid with dissimilar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
