VLDLR

Chr 9AR

very low density lipoprotein receptor

Also known as: CAMRQ1, CARMQ1, CHRMQ1, VLDL-R, VLDLRCH

The protein functions as a multifunctional cell surface receptor that binds and transports VLDL into cells through endocytosis and serves as a critical component of the Reelin signaling pathway, which controls neuronal migration and positioning during brain development. Mutations cause cerebellar hypoplasia with impaired intellectual development and dysequilibrium syndrome, primarily affecting the cerebellum and cognitive function from early childhood. This condition follows autosomal recessive inheritance.

The Badonyi & Marsh prediction model was trained exclusively on dominant disease genes. Predictions are not reliable for genes with autosomal recessive inheritance and are shown at reduced opacity for reference only.
