Genes affected

RABL2B (HGNC:9800): (RAB, member of RAS oncogene family like 2B) The RABL2B protein is a member of the RAB gene family which belongs to the RAS GTPase superfamily. RABL2B is located within a subtelomeric region of 22q13.3. Multiple alternatively spliced transcript variants encoding several different isoforms have been found for this gene.

Ambry Genetics

Mar 21, 2023

The c.472G>A (p.V158I) alteration is located in exon 8 (coding exon 6) of the RABL2B gene. This alteration results from a G to A substitution at nucleotide position 472, causing the valine (V) at amino acid position 158 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
