Genes affected

NSUN2 (HGNC:25994): (NOP2/Sun RNA methyltransferase 2) This gene encodes a methyltransferase that catalyzes the methylation of cytosine to 5-methylcytosine (m5C) at position 34 of intron-containing tRNA(Leu)(CAA) precursors. This modification is necessary to stabilize the anticodon-codon pairing and correctly translate the mRNA. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene.[provided by RefSeq, Mar 2011]

LINC01018 (HGNC:27394): (long intergenic non-protein coding RNA 1018)

ACMG classification

Our verdict: Pathogenic. The variant received 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 5-6611067-G-A is Pathogenic according to our data. Variant chr5-6611067-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 31676.Status of the report is no_assertion_criteria_provided, 0 stars.
