OMIM : ⁵⁶ Coffin-Siris syndrome is a congenital malformation syndrome characterized by developmental delay, intellectual disability, coarse facial features, feeding difficulties, and hypoplastic or absent fifth fingernails and fifth distal phalanges. Other more variable features may also occur. Patients with SMARCB1 mutations may have more severe neurodevelopmental deficits including severe intellectual disability, brain structural abnormalities, and no expressive words, as well as scoliosis (summary by Kosho et al., 2014). For a general phenotypic description and a discussion of genetic heterogeneity of Coffin-Siris syndrome, see CSS1 (135900). (614608)

MalaCards based summary : Coffin-Siris Syndrome 3, also known as mental retardation, autosomal dominant 15, is related to peripheral nerve schwannoma and spinal canal and spinal cord meningioma, and has symptoms including seizures An important gene associated with Coffin-Siris Syndrome 3 is SMARCB1 (SWI/SNF Related, Matrix Associated, Actin Dependent Regulator Of Chromatin, Subfamily B, Member 1), and among its related pathways/superpathways are Glycosaminoglycan metabolism and Chondroitin sulfate/dermatan sulfate metabolism. Affiliated tissues include brain, heart and bone, and related phenotypes are microcephaly and cerebellar hypoplasia

Disease Ontology : ¹² A Coffin-Siris syndrome that has material basis in an autosomal dominant mutation of SMARCB1 on chromosome 22q11.23.

UniProtKB/Swiss-Prot : ⁷³ Coffin-Siris syndrome 3: A form of Coffin-Siris syndrome, a congenital multiple malformation syndrome with broad phenotypic and genetic variability. Cardinal features are intellectual disability, coarse facial features, hypertrichosis, and hypoplastic or absent fifth digit nails or phalanges. Additional features include malformations of the cardiac, gastrointestinal, genitourinary, and/or central nervous systems. Sucking/feeding difficulties, poor growth, ophthalmologic abnormalities, hearing impairment, and spinal anomalies are common findings. Both autosomal dominant and autosomal recessive inheritance patterns have been reported.
