Townes Brocks syndrome is a very rare genetic syndrome with 129 well-documented patients reported in the medical literature.
Townes Brocks syndrome has not been reported before in Iraq. The main aim of this book is to describe the first case of this
syndrome in Iraq which seems to be the case number 130.
Townes Brocks syndrome is a rare autosomal dominant
hereditary disorder which was probably first described in 1972
by Dr Philip L. Townes and Dr Eric Brocks. Dr Philip was professor
of pediatrics at the University of Rochester, and Eric Brocks was
a medical student. The syndrome is characterized by a triad of
imperforate anus, limb defects, and ear abnormalities [1,2].
Main features of the disorder include [1,2]:
a. Anorectal malformations including imperforate anus
(absence of an anal opening), recto-vaginal fistula, anal
stenosis, unusually placed anus.
b. Hand and foot abnormalities including hypoplastic thumbs,
fingerlike thumbs, syndactyly (webbed fingers/toes), fusion of
the wrist bones, overlapping foot and/or toe bones.
c. Abnormalities of the ears with sensori-neural or conductive
hearing impairment or loss or deafness.
d. Other organ abnormalities including hypoplastic kidneys,
multi-cystic kidneys, dysplastic kidneys, and congenital heart
defects such as tetralogy of Fallot and defects of the ventricular
septum.
The main aim of this book is to describe the first case of this
syndrome in Iraq which seems to be the case number 130.
Figure 1: The girl had low set ears and deformity of the right foot with the presence of only three toes. There was no obvious abnormality of left foot, but the big toe was relatively large.
R.J was first seen at about the age of four months during
November 2018 because of poor feeding, failure to thrive, poor
response to sounds, and poor head control. The girl also had low set
ears, and deformity of the right foot with the presence of only three
toes. There was no obvious abnormality of left foot, but the big toe
was relatively large (Figure1). She was delivered at 38 weeks by
cesarean section. She didn’t pass motion and was found to have
imperforated anus. She had colostomy, and the surgeon reported
that the sigmoid was not present. The five-centimeter colon ended
at the pelvis, and cecum found on the left side. Cloaca treated
with diversion colostomy. The parents were relatives and have
three normal children. Echocardiography performed during the
first month showed normal findings. Brain ultrasound performed
on the fifth of August 2018 showed normal findings. Abdominal
ultrasound was also performed on the fifth of August 2018 and
showed small hypoplastic right kidney (18 x 12 mm) with normal
shape. At the age of forty-six days (16, August 2018), a second
abdominal ultrasound showed small hypoplastic right kidney. The
left kidney had normal size.
Authors from Germany, the Netherlands, the UK, the USA,
Belgium, Italy , Switzerland and the Czech republic (Jürgen Kohlhase
et al ,1998; Jürgen Kohlhase et al ,1999) defined Townes Brocks
syndrome as a rare autosomal dominant malformation syndrome
with a combination of anal, renal, limb and ear anomalies. Townes
Brocks syndrome is a very rare genetic syndrome with 129 welldocumented
patients reported in the medical literature [1,2]. In
this paper the first case of this syndrome in Iraq is reported which
is the case number 130.
