A woman was isozygous for a novel mutation in the leukemia inhibitory factor receptor gene (LIFR) (c.2170C>G; p.Pro724Ala) which disrupts LIFR downstream signaling and results in Stüve-Wiedemann syndrome (STWS). She inherited two identical chromosomes 5 from her mother, heterozygous for the LIFR mutation. The presentation was typical for STWS, except there was no long bone dysplasia. Prominent cold-induced sweating and heat intolerance lead to an initial diagnosis of cold-induced sweating syndrome, excluded by exome sequencing. Skin biopsies provide the first human evidence of failed postnatal cholinergic differentiation of sympathetic neurons innervating sweat glands in cold-induced sweating, and of a neuropathy.
