Genes affected
INSC (HGNC:33116): (INSC spindle orientation adaptor protein) In Drosophila, neuroblasts divide asymmetrically into another neuroblast at the apical side and a smaller ganglion mother cell on the basal side. Cell polarization is precisely regulated by 2 apically localized multiprotein signaling complexes that are tethered by Inscuteable, which regulates their apical localization (Izaki et al., 2006 [PubMed 16458856]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 16, 2024The c.868C>T (p.R290W) alteration is located in exon 7 (coding exon 7) of the INSC gene. This alteration results from a C to T substitution at nucleotide position 868, causing the arginine (R) at amino acid position 290 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
