Genes affected

PDXDC2P-NPIPB14P (HGNC:53158): (PDXDC2P-NPIPB14P readthrough, transcribed pseudogene) This locus represents naturally-occurring readthrough transcription between two pseudogenes, PDXDC2P (pyridoxal dependent decarboxylase domain containing 2, pseudogene) and NPIPB14P (nuclear pore complex interacting protein family, member B14, pseudogene). The individual pseudogene loci are not curated as transcribed regions. Readthrough transcripts likely do not encode functional proteins. [provided by RefSeq, Feb 2017]

PDXDC2P (HGNC:27559): (pyridoxal dependent decarboxylase domain containing 2, pseudogene) Predicted to enable carboxy-lyase activity and pyridoxal phosphate binding activity. Predicted to be involved in carboxylic acid metabolic process. Predicted to be active in intracellular membrane-bounded organelle. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.99).
