OMIM®: 57 Liang-Wang syndrome (LIWAS) is a polymalformation syndrome apparent from birth that shows large phenotypic variability and severity. However, all patients have some degree of neurologic dysfunction. The most severely affected individuals have severe global developmental delay with impaired intellectual development and poor or absent speech, marked craniofacial dysmorphism, and visceral and connective tissue abnormalities affecting the bones and vessels. The least severely affected individuals lack seizures, significant dysmorphism, and visceral involvement; they come to attention for neurologic signs and symptoms, including developmental delay with speech delay, strabismus, and/or ataxia. About half of patients have brain imaging anomalies, notably cerebral and cerebellar atrophy and thin corpus callosum, whereas the other half have normal brain imaging (summary by Liang et al., 2019). (618729) (Updated 08-Dec-2022) MalaCards based summary: Liang-Wang Syndrome, also known as liwas, is related to neonatal diabetes and paroxysmal dystonia. An important gene associated with Liang-Wang Syndrome is KCNMA1 (Potassium Calcium-Activated Channel Subfamily M Alpha 1). Affiliated tissues include brain, bone and tongue, and related phenotypes are nystagmus and ataxia UniProtKB/Swiss-Prot: 73 An autosomal dominant syndrome characterized by a highly variable phenotype and severity. The broad spectrum of clinical features includes developmental delay, intellectual disability, ataxia, axial hypotonia, and poor or absent speech, visceral and cardiac malformations, connective tissue presentations with arterial involvement, bone dysplasia and characteristic craniofacial dysmorphism. About half of patients have cerebral and cerebellar atrophy, and thin corpus callosum. |
