Clinical clues to pinpoint the causative gene from the heterogeneous CMT2 and AR‐CMT2 group included pyramidal signs in SACS, MTRFR, and HSPB1, vocal cord paralysis in TRPV4, intellectual disability in MCM3AP, late disease onset in MME, in accordance with previous reports [37, 38, 39, 40]. Here, MCM3AP is linked to Vocal cord paralysis.
