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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 21, 2024The c.1966C>T (p.R656C) alteration is located in exon 14 (coding exon 11) of the RBSN gene. This alteration results from a C to T substitution at nucleotide position 1966, causing the arginine (R) at amino acid position 656 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
