Genes affected

RNF103 (HGNC:12859): (ring finger protein 103) The protein encoded by this gene contains a RING-H2 finger, a motif known to be involved in protein-protein and protein-DNA interactions. This gene is highly expressed in normal cerebellum, but not in the cerebral cortex. The expression of the rat counterpart in the frontal cortex and hippocampus was shown to be induced by elctroconvulsive treatment (ECT) as well as chronic antidepressant treatment, suggesting that this gene may be a molecular target for ECT and antidepressants. The protein is a ubiquitin ligase that functions in the endoplasmic reticulum-associated degradation pathway. Alternative splicing of this gene results in multiple transcript variants. Read-through transcription also exists between this gene and the downstream CHMP3 (charged multivesicular body protein 3) gene. [provided by RefSeq, Oct 2011]

CHMP3-AS1 (HGNC:55795): (CHMP3 and RNF103 antisense RNA 1)

RNF103-CHMP3 (HGNC:38847): (RNF103-CHMP3 readthrough) This locus represents naturally occurring read-through transcription between the neighboring RNF103 (ring finger protein 103) and CHMP3 (charged multivesicular body protein 3) genes. The read-through transcript encodes a fusion protein that shares sequence identity with each individual gene product. [provided by RefSeq, Oct 2011]

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
