Genes affected
MAG (HGNC:6783): (myelin associated glycoprotein) The protein encoded by this gene is a type I membrane protein and member of the immunoglobulin superfamily. It is thought to be involved in the process of myelination. It is a lectin that binds to sialylated glycoconjugates and mediates certain myelin-neuron cell-cell interactions. Three alternatively spliced transcripts encoding different isoforms have been described for this gene. [provided by RefSeq, Nov 2010]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -8 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.55).
BP6
Variant 19-35313292-C-T is Benign according to our data. Variant chr19-35313292-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 568410.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=1}.
BP7
Synonymous conserved (PhyloP=-1.08 with no splicing effect.
BS1
Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0000657 (10/152200) while in subpopulation NFE AF= 0.000147 (10/68020). AF 95% confidence interval is 0.0000791. There are 0 homozygotes in gnomad4. There are 3 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
