Genes affected

SLC13A5 (HGNC:23089): (solute carrier family 13 member 5) This gene encodes a protein belonging to the solute carrier family 13 group of proteins. This family member is a sodium-dependent citrate cotransporter that may regulate metabolic processes. Mutations in this gene cause early infantile epileptic encephalopathy 25. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2014]

ENSG00000290366 (HGNC:):

C17orf100 (HGNC:34494): (chromosome 17 open reading frame 100)
