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]

Feb 15, 2023

The c.877A>T (p.S293C) alteration is located in exon 7 (coding exon 7) of the INSC gene. This alteration results from a A to T substitution at nucleotide position 877, causing the serine (S) at amino acid position 293 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
