Genes affected

RBSN (HGNC:20759): (rabenosyn, RAB effector) This gene encodes a protein that belongs to the FYVE zinc finger family of proteins. The encoded protein interacts with Ras-related proteins that regulate membrane trafficking. A missense mutation in this gene is associated with a defect in the early endocytic pathway. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2014]

The c.1862A>C (p.E621A) alteration is located in exon 14 (coding exon 11) of the RBSN gene. This alteration results from a A to C substitution at nucleotide position 1862, causing the glutamic acid (E) at amino acid position 621 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
