Charcot-Marie-Tooth disease type 2P (CMT2P; MIM #614436) is a specific type of axonal neuropathy caused by mutations in the LRSAM1 gene, which is a RING-type E3 ubiquitin ligase. CMT2P can be inherited in two ways: as an autosomal dominant or autosomal recessive trait. In this report, we describe the clinical characteristics of a family with axonal sensory-motor neuropathy caused by a new variant of the LSRAM1 gene, which is associated with early-onset autosomal dominant CMT2P.
Keywords: Axonal sensory-motor polyneuropathy; Charcot-Marie-Tooth disease type 2P; Dominant inheritance; Heterozygous variant; LRSAM1 gene.
