Genes affected

LOC124901274 (HGNC:):

CASC15 (HGNC:28245): (cancer susceptibility 15) This gene produces a long non-coding RNA that may regulate cell proliferation. This RNA is upregulated in hepatocellular carcinoma, where it is thought to function as an oncogene. However, some splice variants of this gene may function as a tumor suppressor in neuroblastoma and other tumor types. Circular RNA variants were observed at this gene. [provided by RefSeq, Dec 2017]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.92).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.246 is higher than 0.05.
