Protein

Exostosin-like 3

Gene

EXTL3

Organism

Homo sapiens (Human)

Status

Reviewed-Annotation score: -Experimental evidence at protein levelⁱ

Functionⁱ

Glycosyltransferase which regulates the biosynthesis of heparan sulfate (HS). Important for both skeletal development and hematopoiesis, through the formation of HS proteoglycans (HSPGs) (PubMed:28132690, PubMed:28148688). Required for the function of REG3A in regulating keratinocyte proliferation and differentiation (PubMed:22727489).3 Publications

Caution

Involvement in diseaseⁱ

Immunoskeletal dysplasia with neurodevelopmental abnormalities (ISDNA)2 Publications

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionAn autosomal recessive disorder characterized by variable skeletal abnormalities and neurodevelopmental defects. Neurologic manifestations include intellectual disability and motor delay. Some patients manifest hypotonia and seizures. Skeletal features include disproportionate short stature, cervical malformations, epiphyseal and metaphyseal dysplasia, and rarely premature craniosynostosis with progressive microcephaly. Severe combined immunodeficiency with a complete absence of T cells is observed in some patients.
