Variant summary

Our verdict is Likely pathogenic. Variant got 7 ACMG points: 7P and 0B. PS1_ModeratePM5PP2PP3PP5

The NM_006516.4(SLC2A1):ā€‹c.766A>Gā€‹(p.Lys256Glu) variant causes a missense change. The variant allele was found at a frequency of 0.0000409 in 1,613,784 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in Lovd as Likely pathogenic (no stars). Another nucleotide change resulting in same amino acid change has been previously reported as Likely pathogenicin UniProt. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. K256V) 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_pathogenic. Variant got 7 ACMG points.

PS1
Transcript NM_006516.4 (SLC2A1) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in UniProt
PM5
Other missense variant is known to change same aminoacid residue: Variant chr1-42929693-T-A is described in Lovd as [Likely_pathogenic].
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.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.81
PP5
Variant 1-42929694-T-C is Pathogenic according to our data. Variant chr1-42929694-T-C is described in Lovd as [Likely_pathogenic].
