Genes affected

MIAT (HGNC:33425): (myocardial infarction associated transcript) This gene encodes a spliced long non-coding RNA that may constitute a component of the nuclear matrix. Altered expression of this locus has been reported to be associated with a susceptibility to myocardial infarction. It has also been proposed that pathways involving this transcript may contribute to the pathophysiology of schizophrenia. A similar gene in mouse has been associated with retinal cell fate determination. Alternatively spliced transcript variants have been identified. [provided by RefSeq, Dec 2014]

ENSG00000206028 (HGNC:):

MIATNB (HGNC:50731): (MIAT neighbor)

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.88).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.13 is higher than 0.05.
