Genes affected

DTX2P1-UPK3BP1-PMS2P11 (HGNC:42360): (DTX2P1-UPK3BP1-PMS2P11 readthrough, transcribed pseudogene) This locus represents naturally-occurring readthrough transcription spanning multiple pseudogenes: DTX2P1 (DTX2 pseudogene 1), UPK3BP1 (uroplakin 3B pseudogene 1), PMS2P11 (PMS1 homolog 2, mismatch repair system component pseudogene 11). Some transcripts may also extend to PMS2P9 (PMS1 homolog 2, mismatch repair system component pseudogene 9). The readthrough transcripts likely do not encode functional proteins.

ACMG classification

Our verdict: Benign. The variant received -8 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.03).
• BS2: High Homozygotes in GnomAd4 at 46664 gene
