Comment on list classification: Changed rating to Amber so that Green genes on this panel reflect the NHS signed-off version. This will be reviewed at the next GMS panel update.

Gene suggested by Alistair Pagnamenta.

Associated with Osteogenesis imperfecta, type XX, #618644 (AR) in OMIM.

PMID: 31564437 Moosa et al 2019. Report 5 independent consanguineous families with a progressively deforming type of OI. Using WES and prioritising homozygous variants, they found all patients were homozygous for a mutation in the third and final exon of MESD. Parents were heterozygous. Variants were not common polymorphisms. 4 different truncation or frameshift variants were found. In mice, homozygous loss-of-function Mesd mutations cause embryonic lethality during gastrulation (PubMed: 11247670). In functional studies the MESD mutations produce hypomorphic alleles whose failure to remain within the ER significantly reduces but does not completely eliminate LRP5 and LRP6 trafficking.

Alistair Pagnamenta notes that there is a lack of sibling data.
