Presentation
The anomalies are organized by anatomical system and presented in a consistent manner, including details of the clinical presentation, epidemiology, embryology, treatment and prevention for each anomaly. [books.google.com]
These symptoms are rare, however, when there is no other condition present. Brachydactyly is an inherited condition, which makes genetics the main cause. [healthline.com]
Rarely, it presents later in childhood with symptoms of severe constipation and failure to thrive. [orpha.net]
Hand abnormalities were not present in any other family members, and the obligate heterozygous females were without gastrointestinal problems. [pediatrics.aappublications.org]
Presentation with early sudden neonatal death is rare but should be considered in the diagnostic work-up of sudden deaths in this age group. [link.springer.com]
Treatment
Management and treatment Treatment is surgical. It consists in resection of the aganglionic segment followed by anastomosis of the proximal bowel to the anal margin (''pullthrough''). [orpha.net]

It has been described in four males from one family (two brothers and two mater / 721222007 enanismo con braquidactilia, tipo Mseleni Mseleni joint disease SNOMEDCT-ES (trastorno) / 715470008 SNOMEDCT-ES (treatment) / 715470008 braquidactilia brachydactylia [wordscope.com]
You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments. [rarediseases.info.nih.gov]
Unless there is an accompanying disorder that produces symptoms, or the shortened digits impair the use of hands and feet, there is no treatment needed for brachydactyly. [healthline.com]
Prognosis
Prognosis Overall prognosis is good in most cases, despite issues with constipation and continence even following surgical correction. [orpha.net]
Etiology
Etiology Hirschsprung disease genes RET GDNF NTRN SOX10 EDNRB EDN3 ECE1 ZFHX1B phox2b TCF4 HSCR1: dominant mutations in the RET gene (MIM.164761) in 3% of isolated sporadic Hirschsprung’s disease HSCR2 at 13q22: recessive mutation in the EDNRB gene coding [humpath.com]
Etiology HSCR is a neurocristopathy and is due to a defect in the development of the enteric nervous system. It is characterized by the absence of neuronal ganglion cells (Cajal cells) (aganglionosis) in the terminal part of the intestine. [orpha.net]

Changes in either the EDNRB gene or the EDN3 gene disrupt the normal functioning of the endothelin receptor type B or the endothelin 3 protein, preventing them from transmitting signals important for the development of enteric nerves. [ghr.nlm.nih.gov]
