Genetic Variant AP4B1-AS1:n.246+14730G>A (chr1-113872746-G-A) – ACMG Classification: Likely_benign (-4 pts)

Variant summary

Our verdict is The variant received -4 classification points (ACMG Germline Pathogenicity v2019). BP4_Strong

The NR_037864.1(AP4B1-AS1):n.246+14730G>A variant causes a intron change involving the alteration of a non-conserved nucleotide. Note: NR_037864.1 is not a MANE Select or MANE Plus Clinical transcript for AP4B1-AS1; the reported annotation may differ from that of the MANE-designated reference transcript for this gene. No reliable population frequency data is available for this variant in the gnomAD database. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.
