Genes affected
IQCJ (HGNC:32406): (IQ motif containing J)
IQCJ-SCHIP1 (HGNC:38842): (IQCJ-SCHIP1 readthrough) This locus represents naturally occurring read-through transcription from the neighboring IQ motif containing J (IQCJ) and schwannomin interacting protein 1 (SCHIP1) genes. Alternative splicing results in multiple transcript variants that are composed of in-frame exons from each individual gene. The resulting fusion products are thought to be components of the multimolecular complexes of axon initial segments and nodes of Ranvier, and they may play a role in calcium-mediated responses.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 19, 2024The c.179A>G (p.Y60C) alteration is located in exon 4 (coding exon 4) of the IQCJ gene. This alteration results from a A to G substitution at nucleotide position 179, causing the tyrosine (Y) at amino acid position 60 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
