A Hypothesis

by Hugh Rienhoff last modified Oct 16, 2007 01:00 PM

An in-depth but sometimes speculative discussion of how genetic alterations in the genes of the TGF beta super family of hormones and receptors influence human health.

On POSSUM, when I put in the terms

Hypertelorism

Bifid uvula

[Hypomyoplasia] -- hypotonia or muscle

weakness/myopathy

Arachnodactyly

Arthrogryposis (or contractures)

Blue sclerae

 

, I get this differential:

Baller-Gerold syndrome

monosomy 21

terminal deletion 4q

Marden Walker syn

Marfan syn

Roberts syn

Shpritzen-Goldberg syn

 

 

 

 

 

 

London gives me over a thousand if you only require one search term to be

present and none are "mandatory". When I made bifid uvula a mandatory

(which of all the features made the most sense to be mandatory), I get 24

disorders:

 

Ritscher-Schinzel - Dandy-Walker; atrioventricular septal defect

Willems (1984) - short limbs, subluxed knees, cleft palate

Baller-Gerold

10q26 del

22q11.2 microdup

Lewandowski (1980) - short stature, multiple vertebral anomalies

Oro-facial-digital syn - type Gabrielli

Pfieffer syn

Van Staey (1990) - craniofacial anomalies, deafness, vermis hypoplasia

acrofacial dystosis - post axial defects

Bazopoulou-Kyrkanidou (1995) - ptosis, subvalvular aortic stenosis

Beare-Stevenson syn

Crouzon

Di George

Elsahy-Waters-branchioskeletogenital syn

Francois (1973) - agenesis of the corpus callosum, coloboma, vermis aplasia

Fryns

Osteopathia striata - cranial sclerosis

Pierre Robin sequence

Rubinstein Taybi

Serpentine fibula syndrome

Stankler (1982) - diarrhea, unusual facies, abnormal scalp hair

Zuncih (1983) - ichthyosis, cleft palate, MR, coloboma of the retina
