Genes affected

TSNAX-DISC1 (HGNC:49177): (TSNAX-DISC1 readthrough (NMD candidate)) This gene represents naturally occurring read-through transcription between the neighboring TSNAX (translin-associated factor X) and DISC1 (disrupted in schizophrenia 1) genes on chromosome 1. Alternative splicing results in multiple transcript variants, all of which are candidates for nonsense-mediated mRNA decay (NMD) and are unlikely to be protein-coding. These alterations in gene processing may be associated with risk for psychiatric illness, most notably, schizophrenia. [provided by RefSeq, Nov 2010]

LINC00582 (HGNC:43842): (long intergenic non-protein coding RNA 582)

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.84).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.625 is higher than 0.05.
