Unbalanced X;Autosome Translocations May Lead to Mild Phenotypes and Are Associated with Autoimmune Diseases.
CYTOGENETIC AND GENOME RESEARCH(2020)
Abstract
Unbalanced X;autosome translocations are a rare occurrence with a wide variability in clinical presentation in which the X chromosome unbalance is usually mitigated by a favorable X inactivation pattern. In most cases, this compensation mechanism is incomplete, and the patients show a syndromic clinical presentation. We report the case of a family with 4 women, of 3 different generations, carrying an unbalanced X;7 translocation with a derivative X;7 chromosome and showing a skewed X inactivation pattern with a preferential activation of the normal X. None of the carriers show intellectual disability, and all of them have a very mild clinical presentation mainly characterized by gynecological/hormonal issues and autoimmune disorders. We underline the necessity of family testing for a correct genetic consultation, especially in the field of prenatal diagnosis. We indeed discuss the fact that X;autosome translocations may lead to self-immunization, as skewed X chromosome inactivation has already been proved to be related to autoimmune disorders.
