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 c.265T>C (p.Y89H) alteration is located in exon 4 (coding exon 3) of the MEPE gene. This alteration results from a T to C substitution at nucleotide position 265, causing the tyrosine (Y) at amino acid position 89 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
