Genes affected

CASC19 (HGNC:49476): (cancer susceptibility 19)

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]

CCAT1 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.78).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.274 is higher than 0.05.
