Genes affected
MFAP2 (HGNC:7033): (microfibril associated protein 2) Microfibrillar-associated protein 2 is a major antigen of elastin-associated microfibrils and a candidate for involvement in the etiology of inherited connective tissue diseases. Four transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Sep 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 19, 2022The c.278G>A (p.G93E) alteration is located in exon 6 (coding exon 5) of the MFAP2 gene. This alteration results from a G to A substitution at nucleotide position 278, causing the glycine (G) at amino acid position 93 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
