MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] GM2 and GD2 gangliosides are sialic acid-containing glycosphingolipids. GalNAc-T is the enzyme involved in the biosynthesis of G(M2) and G(D2) glycosphingolipids. GalNAc-T catalyzes the transfer of GalNAc into G(M3) and G(D3) by a beta-1,4 linkage, resulting in the synthesis of G(M2) and G(D2), respectively. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2013]
PHENOTYPE: Mice homozygous for one knock-out allele lack all complex gangliosides but show normal brain histology and gross behavior with only subtle defects in neural conduction velocities. Mice homozygous for another knock-out allele exhibit male infertility due to degeneration of the seminiferous tubules. [provided by MGI curators]
