FGFBP1

Chr 4

fibroblast growth factor binding protein 1

Also known as: FGF-BP, FGF-BP1, FGFBP, FGFBP-1, HBP17

The encoded protein is a secreted carrier protein that binds to and releases fibroblast growth factors from the extracellular matrix, enhancing their mitogenic activity and signaling during tissue repair and angiogenesis. Mutations in FGFBP1 cause autosomal recessive intellectual disability with microcephaly, seizures, and brain malformations including simplified gyral pattern and corpus callosum abnormalities. The gene shows moderate constraint against loss-of-function variants (pLI 0.59, LOEUF 1.06), and affected individuals typically present in infancy with developmental delays and neurological symptoms.
