Genes affected
SLC2A1 (HGNC:11005): (solute carrier family 2 member 1) This gene encodes a major glucose transporter in the mammalian blood-brain barrier. The encoded protein is found primarily in the cell membrane and on the cell surface, where it can also function as a receptor for human T-cell leukemia virus (HTLV) I and II. Mutations in this gene have been found in a family with paroxysmal exertion-induced dyskinesia. [provided by RefSeq, Apr 2013]

GLUT1 deficiency syndrome 1, autosomal recessive Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jan 30, 2023 | This premature translational stop signal has been observed in individual(s) with SLC2A1-related conditions (PMID: 23801573). For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 1027520). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Gln46*) in the SLC2A1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SLC2A1 are known to be pathogenic (PMID: 21832227, 26193382). - |
