Genes affected

AFAP1-AS1 (HGNC:28141): (AFAP1 antisense RNA 1) This gene produces a long non-coding RNA that is overexpressed in tumor cells and may promote cancer cell metastasis. [provided by RefSeq, Dec 2017]

AFAP1 (HGNC:24017): (actin filament associated protein 1) The protein encoded by this gene is a Src binding partner. It may represent a potential modulator of actin filament integrity in response to cellular signals, and may function as an adaptor protein by linking Src family members and/or other signaling proteins to actin filaments. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2008]

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.736 is higher than 0.05.
