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 ...
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.
[1] [2] [3] Nevertheless, the musculoskeletal features are central to the diagnosis of some syndromes such as Proteus syndrome. [2] The time of presentation of children with overgrowth syndromes is an important contributor to the differential diagnosis.
Beckwith-Wiedemann syndrome (BWS), an overgrowth syndrome is a well-recognized form of syndromic HI. Other syndromes that commonly feature HI include Kabuki syndrome and Turner syndrome . Most individuals with syndromic HI respond to treatment with diazoxide and HI may resolve over time.
Omphalocele occurs in 1 in 4,000 births and is associated with a high rate of mortality (25%) and severe malformations, such as cardiac anomalies (50%), neural tube defect (40%), exstrophy of the bladder and Beckwith–Wiedemann syndrome. Approximately 15% of live-born infants with omphalocele have chromosomal abnormalities.
Perlman syndrome is caused by mutations in the DIS3L2 gene found on chromosome 2 at 2q37.2. DIS3L2 is involved in RNA degradation and cell cycle control. [ 6 ] PS is genetically distinct from Beckwith–Wiedemann syndrome and Simpson–Golabi–Behmel syndrome , which are caused by mutations in 11p15.5 and GPC3 respectively. [ 1 ]
