Genes affected

IRF2BPL (HGNC:14282): (interferon regulatory factor 2 binding protein like) This gene encodes a transcription factor that may play a role in regulating female reproductive function. [provided by RefSeq, Jun 2012]

LINC02289 (HGNC:53205): (long intergenic non-protein coding RNA 2289)

ACMG classification

Our verdict: Pathogenic. The variant received 12 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. Fraction of 0.0648 CDS is truncated, and there are 2 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 14-77025555-ACT-A is Pathogenic according to our data. Variant chr14-77025555-ACT-A is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 872574.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
