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]

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]

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]
