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]
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.
Establishing a diagnosis is important because hemihyperplasia is associated with an increased risk for embryonal tumors, mainly Wilms tumor and hepatoblastoma. [3] Due to the heightened tumor risk, a tumor screening protocol is recommended for all children with isolated hemihyperplasia and Beckwith-Wiedemann Syndrome. Some of the other ...
The time of presentation of children with overgrowth syndromes is an important contributor to the differential diagnosis. Children with some overgrowth syndromes such as Klippel–Trénaunay syndrome can be readily detectable at birth. [ 3 ]
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]
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.
