Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PM2 BP4_Strong

The NM_014575.4(SCHIP1):​c.496G>T​(p.Val166Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000028 in 1,428,080 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict 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. V166M) has been classified as Uncertain significance.

Genes affected

SCHIP1 (HGNC:15678): (schwannomin interacting protein 1) Enables identical protein binding activity. Predicted to be involved in positive regulation of hippo signaling. Predicted to act upstream of or within several processes, including animal organ development; face morphogenesis; and fibroblast migration. Located in several cellular components, including cell junction; cytosol; and nuclear body. [provided by Alliance of Genome Resources, Apr 2022]

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.

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.060304046).
