Genes affected

RAB41 (HGNC:18293): (RAB41, member RAS oncogene family) This gene encodes a small GTP-binding protein that belongs to the largest family within the Ras superfamily. These proteins function as regulators of membrane trafficking. They cycle between inactive GDP-bound and activated GTP-bound states, which is controlled by GTP hydrolysis-activating proteins (GAPs). This family member can be activated by the GAP protein RN-Tre, and it is localized to the Golgi complex. [provided by RefSeq, May 2010]

RAB41 links:

PDZD11 (HGNC:28034): (PDZ domain containing 11) Enables protein C-terminus binding activity. Involved in pore complex assembly. Located in basolateral plasma membrane and cytosol. Part of pore complex. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Feb 13, 2024

The c.122G>A (p.S41N) alteration is located in exon 1 (coding exon 1) of the RAB41 gene. This alteration results from a G to A substitution at nucleotide position 122, causing the serine (S) at amino acid position 41 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
