Ichthyosis is a family of rare genetic skin disorders characterized by dry, thickened, scaly skin. There are more than 20 types of ichthyosis which range in severity. Las ictiosis congénitas autosómicas recesivas (ICAR) son trastornos infrecuentes de la queratinización que se engloban en las formas no sindrómicas de. Describimos el caso de un paciente de 32 años de edad que desde el nacimiento presentaba dermatosis ictiosiforme generalizada, queratodermia.

A population-based study using the capture-recapture method in Spain. Serial single- gene testing can be considered if multi-gene panel testing is not available; the order of testing is determined by the genes in which pathogenic variants most commonly occur for a given phenotype. To date, 22 distinct sequence variants in SLC27A4 have been reported as pathogenic in individuals with ichthyosis-prematurity syndrome IPS. The most common or well-known types are as follows: The protein is highly expressed in brain, lung, stomach, leukocytes, and keratinocytes.
