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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -17 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.57).
BP6
Variant 1-42930635-G-A is Benign according to our data. Variant chr1-42930635-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 139158.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=0.511 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000972 (148/152324) while in subpopulation AFR AF = 0.00313 (130/41562). AF 95% confidence interval is 0.00269. There are 0 homozygotes in GnomAd4. There are 62 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
