Genes affected

SLC35A3 (HGNC:11023): (solute carrier family 35 member A3) This gene encodes a UDP-N-acetylglucosamine transporter found in the golgi apparatus membrane. In cattle, a missense mutation in this gene causes complex vertebral malformation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2012]

LOC124904230 (HGNC:):

ACMG classification
