Genes affected

IRAIN (HGNC:50365): (IGF1R antisense imprinted non-protein coding RNA) This gene expresses a long non-coding RNA in antisense to the insulin-like growth factor type I receptor (IGF1R) gene. This transcript is imprinted and expressed from the paternal allele. It interacts with chromatin and may promote long-range DNA interactions that influence the regulation of gene expression.

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.84).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.336 is higher than 0.05.
