Figure 1. Identification of a CMT2-associated INSC variant.

Figure 1

(A) Schematic figure of asymmetric cell division in neuroblast. Inscuteable (INSC), an adaptor protein in asymmetric cell division, regulates microtubules by binding with PAR3 and LGN. (B) The INSC p.Met70Arg variant resides in the LGN-binding domain of the human INSC protein. (C) The CMT2 pedigree carrying the INSC mutation. “M” represents the INSC mutant allele, and “W” stands for wild-type allele. Open symbol: unaffected; filled symbol: affected; symbol with a diagonal line: deceased; arrow: proband; squares: males; circles: females; brackets with dashed line: adopted into the pedigree. (D) Sanger sequencing traces confirming the c. 290 T > G (p.Met70Arg, M70R) variant.
