Summaries for Chromosome 2q37 Deletion Syndrome

OMIM : 57 Patients with chromosome 2q37 deletion syndrome show highly variable clinical manifestations likely resulting from different deletion sizes and deletions of different genes. Variable clinical features included brachydactyly type E (BDE), affecting the metacarpals and metatarsals (in about 50% of patients), short stature, mild to moderate intellectual disability, behavioral abnormalities, and dysmorphic facial features. However, many individuals with deletions do not show cognitive deficits (summary by Villavicencio-Lorini et al., 2013, Wheeler et al., 2014, Jean-Marcais et al., 2015). (600430)

MalaCards based summary : Chromosome 2q37 Deletion Syndrome, also known as brachydactyly-mental retardation syndrome, is related to 2q37 deletion syndrome and thumbs, stiff, with brachydactyly type a1 and developmental delay. An important gene associated with Chromosome 2q37 Deletion Syndrome is HDAC4 (Histone Deacetylase 4). Affiliated tissues include heart, eye and kidney, and related phenotypes are macrocephaly and short neck

UniProtKB/Swiss-Prot : 75 Brachydactyly-mental retardation syndrome: A syndrome resembling the physical anomalies found in Albright hereditary osteodystrophy. Common features are mild facial dysmorphism, congenital heart defects, distinct brachydactyly type E, mental retardation, developmental delay, seizures, autism spectrum disorder, and stocky build. Soft tissue ossification is absent, and there are no abnormalities in parathyroid hormone or calcium metabolism.
