Genes affected

ARL8B (HGNC:25564): (ADP ribosylation factor like GTPase 8B) Enables guanyl ribonucleotide binding activity and tubulin binding activity. Involved in several processes, including calcium ion regulated lysosome exocytosis; lysosomal transport; and vesicle fusion. Located in cytolytic granule membrane; midbody; and spindle midzone. Colocalizes with lysosomal membrane. [provided by Alliance of Genome Resources, Apr 2022]

ENSG00000233912 (HGNC:):

ACMG classification

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