Green List (high evidence)

8 families described in total. The B4GALNT1 gene encodes beta-1,4-N-acetylgalactosaminyl transferase-1 (EC, an enzyme involved in the biosynthesis of complex gangliosides (G), which are mono- (M), di- (D), and tri- (T) sialic acid-containing glycosphingolipids generated by sequential glycosylations. (OMIM). 5 families with different homozygous variants described with complex hereditary spastic paraplegia (PMID: 23746551). Another 3 families with homozygous variants and progressive weakness and spasticity were described in PMID:24103911.
