Preferred Label : Marsili syndrome;
Symbol : MARSIS;
CISMeF acronym : MARSIS;
Type : Phenotype, molecular basis known;
Alternative titles and symbols : Congenital analgesia, autosomal dominant; Insensitivity to pain, congenital, autosomal dominant;
Description : Dyck et al. (1983) noted that congenital 'indifference' to pain, which is characterized
by an absence of nerve pathology, must be distinguished from congenital 'insensitivity'
to pain, which is associated with pathologic changes in peripheral nerves. Many cases
reported as congenital indifference to pain or congenital analgesia were reported
before the development of methods to assess the physiologic function of nerve fibers;
therefore, Dyck et al. (1983) suggested that some of these cases may actually have
been a hereditary sensory and autonomic neuropathy, such as HSAN4 (256800) or HSAN5
(608654). For a phenotypic description of congenital indifference to pain, see the
autosomal recessive form (243000), which is more common. Ervin and Sternbach (1960)
reported 6 affected persons in 2 generations, consistent with autosomal dominant inheritance.
Comings and Amromin (1974) described the disorder in a mother and a son and daughter,
with a possibility of the disorder having been present in an earlier generation. Landrieu
et al. (1990) reported a mother and daughter with possible dominant inheritance of
indifference to pain; perception of the other sensory modalities was normal, as was
the remainder of the neurologic examination. Electrophysiologic studies and morphometric
evaluation of myelinated and unmyelinated fibers from nerve biopsy specimens were
normal, and the authors concluded that the disorder was not a variety of;
