Report of a Patient with Multiple Mutations Leading to CharcotMarie-Tooth Disease and Distal Spinal Muscular Atrophy: A Case Report

Abstract

The Charcot-Marie-Tooth disease is a group of progressive disorders that affects the peripheral nerves and results in loss of sensation and atrophy of muscles in lower limbs. There are several types of Charcot-Marie-Tooth and multiple genes are associated with this disease. Distal spinal muscular atrophy is an extremely rare disorder characterized by progressive pure lower motor neuron involvement. A 24 yr old woman using wheelchair referred to Farhud Genetic Clinic, Tehran, Iran in 2019, with progressive muscular atrophy, pain and Electromyography test suggesting Charcot-Marie-tooth. Both feet and hands were involved. Whole exome sequencing was performed on extracted DNA from her blood sample. We report the first case of a patient with different types of CharcotMarie-Tooth and distal spinal muscular atrophy simultaneously, which are as a result of mutations in multiple genes; this case is very uncommon.
