Genes affected

CASC8 (HGNC:45129): (cancer susceptibility 8)

POU5F1B (HGNC:9223): (POU class 5 homeobox 1B) This intronless gene was thought to be a transcribed pseudogene of POU class 5 homeobox 1, however, it has been reported that this gene can encode a functional protein. The encoded protein is nearly the same length as and highly similar to the POU class 5 homeobox 1 transcription factor, has been shown to be a weak transcriptional activator and may play a role in carcinogenesis and eye development. [provided by RefSeq, Apr 2009]

PCAT1 (HGNC:43022): (prostate cancer associated transcript 1) This gene produces a long non-coding RNA that promotes cell proliferation and is upregulated in prostate, colorectal, and other cancers. This RNA negatively regulates the BRCA2 tumor suppressor protein and positively regulates Myc oncoprotein. It contains binding sites for microRNAs, and may act as a sponge for microRNAs that regulate cell growth pathways. [provided by RefSeq, Dec 2017]

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.86).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.695 is higher than 0.05.
