Genes affected

RAB43 (HGNC:19983): (RAB43, member RAS oncogene family) Enables GTPase activity. Involved in several processes, including Golgi organization; phagosome maturation; and retrograde transport, plasma membrane to Golgi. Located in Golgi apparatus and phagocytic vesicle. [provided by Alliance of Genome Resources, Apr 2022]

ISY1-RAB43 (HGNC:42969): (ISY1-RAB43 readthrough) This locus represents naturally occurring read-through transcription between the neighboring ISY1 (ISY1 splicing factor homolog) and RAB43 (RAB43, member RAS oncogene family) gene on chromosome 3. The read-through transcript encodes a protein that shares sequence identity with the upstream gene product, but its C-terminus is distinct due to a frameshift relative to the downstream gene.

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.74).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.968 is higher than 0.05.
