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 ...
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.
Children with some overgrowth syndromes such as Klippel–Trénaunay syndrome can be readily detectable at birth. [3] In contrast, other overgrowth syndromes such as Proteus syndrome usually present in the postnatal period, characteristically between the second and third year of life. [ 2 ]
Beckwith-Wiedemann Syndrome: Abnormal regulation of chromosome 11p15.5 7% Characterized by macrosmia (large birth size), macroglossia (large tongue), hemihypertrophy (one side of the body is larger), other tumors in body, omphalocele (open abdominal wall) and visceromegaly (enlargement of organs inside abdomen). [16]
Diastasis recti, hernias, and omphalocele have all been described in conjunction with the pentalogy. [2] Sternal defects too have a range of presentations, from absence of the xiphoid process to shortened or cleft sternum. If the sternal defect is large enough, the neonate may have ectopia cordis, in which the heart is located outside of the ...
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 ...
A condition plaintiffs allege they received from the vaccine is postural orthostatic tachycardia syndrome (POTS). The chronic disorder presents as dizziness or fainting after reduced blood volume ...
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]
