Cold-induced sweating syndrome: CISS1 and CISS2 Manifestations from infancy to adulthood. Four new cases
ABSTRACT Cold-induced sweating syndrome (CISS), a rare autosomal recessive disorder, is genetically heterogeneous. Deficiency of the CRLF1 and the CLCF1 gene functions results in CISS1 and CISS2, respectively. So far, only a single patient with CISS2 has been reported. Here we describe four new cases of CISS, two additional patients with CISS2 (confirming locus heterogeneity) and two patients with CISS1. Their case histories are given in detail to emphasize the striking similarity of their presentation, which makes a clinical differentiation impossible. All four cases had a uniform presentation in the neonatal period, much like Crisponi syndrome - inability to suckle and swallow due to facial and bulbar weakness; excessive startle and trismus-like facial contractions when crying or being handled; apnoeic spells; episodic unexplained fevers (up to 41 degrees C) and associated seizures or even sudden death; erythematous skin rashes; and camptodactyly. Thus it is evident that Crisponi syndrome is the pediatric manifestation of both CISS1 and CISS2. Signs abate during infancy and most children have a normal psychomotor development. During the first decade all children develop scoliosis and abnormal sweating which is the most disabling symptom in adulthood. We report that cold-induced sweating can be effectively treated. Detailed clinical observations, correlated with the findings from basic science research, may serve to elucidate the role(s) of this important cytokine complex in embryonic and postnatal development.

Other CS/CISS1 patients have been identified in Eastern countries, in particular in India [Thomas et al., 2008], Pakistan [this report], Yemen [Dagoneau et al., 2007], Saudi Arabia [this report], and Japan [Yamazaki et al., 2010], whereas in the Western states, 1 patient has been identified in Canada [Hahn et al., 2006], 1 in Australia [this report], and 1 in USA [Hahn et al., 2010].

ABSTRACT: Crisponi syndrome (CS) and cold-induced sweating syndrome type 1 (CISS1) share clinical characteristics, such as dysmorphic features, muscle contractions, scoliosis and cold-induced sweating, with CS patients showing a severe clinical course in infancy involving hyperthermia associated with death in most cases in the first years of life. To date 24 distinct CRLF1 mutations have been found either in homozygosity or in compound heterozygosity in CS/CISS1 patients, with the highest prevalence in Sardinia, Turkey and Spain. By reporting 11 novel CRLF1 mutations, here we expand the mutational spectrum of CRLF1 in the CS/CISS1 syndrome to a total of 35 variants and present an overview of the different molecular and clinical features of all of them. To catalogue all the 35 mutations we created a CRLF1 mutations database, based on the Leiden Open (source) Variation Database (LOVD) system (https://grenada.lumc.nl/LOVD2/mendelian_genes/variants). Overall, the available functional and clinical data support the fact that both syndromes actually represent manifestations of the same autosomal recessive disorder caused by mutations in the CRLF1 gene. Therefore, we propose to rename the two overlapping entities with the broader term of Crisponi/CISS1 syndrome. This article is protected by copyright.

ABSTRACT: Cold-induced sweating syndrome (CISS) is a rare autosomal recessive disorder characterized by excess sweating induced by cold exposure, camptodactyly and kyphoscoliosis. CISS is genetically heterogeneous. Deficiency of the CRLF1 or the CLCF1 gene function results in one of two clinically indistuinguishable disorders called CISS1 and CISS2, respectively. We present two Turkish brothers (22 and 13years old) who had excess sweating induced by cold exposure, severe dorsal scoliosis, camptodactyly, reduced pain sensitivity and marfanoid habitus. The patients were homozygous and their parents heterozygous for a novel missense mutation c.413C>T (p.Pro138Leu) in CRLF1 gene. The cranial magnetic resonance imaging (MRI) of two patients also showed multiple small hyperintense lesions in the subcortical white matter. Similar MRI finding has also been reported in a Japanese woman with CISS1 and marfanoid habitus. The lesions found in the present cases showed no characteristic features. However, multiple small hyperintense lesions in subcortical white matter on T2 weighted and fluid attenuation inversion recovery (FLAIR) images may support the clinical diagnosis of CISS.Brain & development 09/2012; 35(6).

ABSTRACT: Crisponi syndrome is a recently described rare autosomal recessive disorder. The main clinical features of the syndrome are neonatal onset of episodic contractions of the facial muscles with trismus and abundant salivation resembling a tetanic spasm. Herein, we report a case of 3-day-old male neonate presenting with trismus, abundant salivation, feeding difficulties, camptodactyly, and hyperthermia, which are consistent with the diagnostic criteria of Crisponi syndrome. The parents of the patient were consanguineous, supporting autosomal recessive inheritance. Molecular analysis revealed a homozygous mutation in cytokine receptor-like factor-1 gene in the patient.Clinical dysmorphology 06/2011; 20(4):187-9.
