Beckwith–Wiedemann syndrome (/ ˈ b ɛ k ˌ w ɪ θ ˈ v iː d ə. m ə n /; abbreviated BWS) is an overgrowth disorder usually present at birth, characterized by an increased risk of childhood cancer and certain congenital features. A minority (<15%) of cases of BWS are familial, meaning that a close relative may also have BWS, and parents ...
Beckwith–Wiedemann syndrome, caused by abnormal methylation in the maternal ICE region, causing Igf2 overexpression. Symptoms include accelerated growth, abnormal growth (hemihyperplasia), abdominal wall defects, macroglossia , hypoglycemia , kidney abnormalities, and large abdominal organs.
Other conditions, such as Beckwith–Wiedemann syndrome, are associated with abnormalities of imprinted genes on the short arm of chromosome 11. Chromosome 14 is also known to cause particular symptoms such as skeletal abnormalities, intellectual disability, and joint contractures, among others. [7] [8]
Presence of neurological abnormality or macrocephaly can suggest macrocephaly-capillary malformation syndrome. Hemihypertrophy-multiple lipomatosis or Beckwith–Wiedemann syndrome are diseases with total hypertrophy and are associated with an increased risk of Wilms' tumor. [26] [27] About 10% of DCMO cases present with total hemihypertrophy. [3]
Hemihyperplasia is seen in several congenital syndromes including Beckwith-Wiedemann syndrome and Russell-Silver syndrome. [2] Hemihyperplasia is a congenital overgrowth disorder, and the asymmetry can range from mild to severe.
John Bruce Beckwith (September 18, 1933 – January 21, 2025) was an American pediatric pathologist known for helping to identify Beckwith-Wiedemann syndrome, which is partly named after him. He is also known for his role as reference pathologist for the National Wilms Tumor Study Group , a position he held from 1969 until his retirement thirty ...
Genetic disorders of overgrowth (e.g. Beckwith–Wiedemann syndrome, Sotos syndrome, Perlman syndrome, Simpson-Golabi-Behmel syndrome) are often characterized by macrosomia. [ 25 ] [ 26 ] Other risk factors
