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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2021The c.2038A>T (p.I680F) alteration is located in exon 14 (coding exon 11) of the RBSN gene. This alteration results from a A to T substitution at nucleotide position 2038, causing the isoleucine (I) at amino acid position 680 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
