Genes affected

MEPE (HGNC:13361): (matrix extracellular phosphoglycoprotein) This gene encodes a secreted calcium-binding phosphoprotein that belongs to the small integrin-binding ligand, N-linked glycoprotein (SIBLING) family of proteins. Members of this family are components of the extracellular matrix of bone and dentin and regulate bone mineralization. Deficiency of a similar protein in mouse results in increased bone mass. Mice lacking this gene are resistant to aging-related trabecular bone loss. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2014]

The MEPE c.458G>A variant is predicted to result in the amino acid substitution p.Gly153Glu. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.032% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/4-88766385-G-A). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
