Variant summary

Our verdict is Likely benign. Variant got -3 ACMG points: 3P and 6B. PM1PP2BP4_StrongBP6_Moderate

The NM_006516.4(SLC2A1):​c.1216G>A​(p.Val406Ile) variant causes a missense change. The variant allele was found at a frequency of 0.0000539 in 1,614,150 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V406F) has been classified as Uncertain significance.

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 made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PM1
In a hotspot region, there are 5 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 7 uncertain in NM_006516.4
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), SLC2A1. . Gene score misZ 2.9256 (greater than the threshold 3.09). Trascript score misZ 4.6729 (greater than threshold 3.09). GenCC has associacion of gene with childhood absence epilepsy, dystonia 9, epilepsy, idiopathic generalized, susceptibility to, 12, GLUT1 deficiency syndrome, myoclonic-astatic epilepsy, childhood onset GLUT1 deficiency syndrome 2, hereditary cryohydrocytosis with reduced stomatin, encephalopathy due to GLUT1 deficiency.
BP4
Computational evidence support a benign effect (MetaRNN=0.046082467).
BP6
Variant 1-42927667-C-T is Benign according to our data. Variant chr1-42927667-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 207230.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr1-42927667-C-T is described in Lovd as [Likely_benign].
