Genetic Variant IQCJ:p.Arg63Gln (chr3-159262580-G-A) – ACMG Classification: Likely_benign (-2 pts)

Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4_Moderate

The NM_001042706.3(IQCJ):c.188G>A(p.Arg63Gln) variant causes a missense change. The variant allele was found at a frequency of 0.0000775 in 1,613,684 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R63W) has been classified as Uncertain significance.

Genes affected

IQCJ (HGNC:32406): (IQ motif containing J)

IQCJ links:

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.
