ICD10 code of Dubowitz syndrome and ICD9 code

TL;DR: Dubowitz syndrome is classified under the ICD-10 code Q87.89 (other specified congenital malformation syndromes) and the ICD-9 code 759.89 (other specified congenital anomalies). Because Dubowitz syndrome is a rare, genetically heterogeneous condition, it does not have a unique, disease-specific code in either system, but rather falls under broader categories for rare congenital syndromes.

What exactly is Dubowitz syndrome?

Dubowitz syndrome is a rare multisystem disorder characterized by a combination of intrauterine growth retardation, short stature, microcephaly (an abnormally small head), and distinctive facial features. Individuals with Dubowitz syndrome often exhibit a high-pitched voice, sparse hair, and dermatological issues like eczema. While the exact prevalence of Dubowitz syndrome remains unknown, it is estimated to be extremely rare, with fewer than 200 cases reported in medical literature globally. Within the DiseaseMaps.org community, six individuals are currently sharing their journey with this condition, highlighting the importance of connecting with others who face similar diagnostic challenges.

How is Dubowitz syndrome diagnosed in a clinical setting?

Diagnosis of Dubowitz syndrome is primarily clinical, meaning it is based on the recognition of physical traits and developmental patterns rather than a single definitive laboratory test. Because there is no single gene identified as the exclusive cause for all cases of Dubowitz syndrome, physicians often use a process of exclusion. Genetic testing, specifically chromosomal microarray or whole-exome sequencing, is frequently utilized to rule out other conditions that share overlapping symptoms. A specialist physician, typically a clinical geneticist, will evaluate the patient for the following diagnostic pillars commonly seen in Dubowitz syndrome:

• Severe prenatal and postnatal growth restriction.


• Distinctive craniofacial features, including ptosis (drooping eyelids), epicanthal folds, and a broad nasal bridge.


• Developmental delays and intellectual disability ranging from mild to severe.


• Behavioral characteristics, such as hyperactivity and a short attention span.


• Feeding difficulties, particularly in infancy, which may require specialized nutritional support.

Is there a known genetic cause for Dubowitz syndrome?

The inheritance pattern of Dubowitz syndrome is widely considered to be autosomal recessive, though this remains a subject of ongoing research due to the clinical variability observed in patients. Because a single causative gene has not been universally identified, the diagnosis of Dubowitz syndrome is sometimes debated in the literature; some experts suggest that what we label as Dubowitz syndrome may actually be a spectrum of different, yet-to-be-identified genetic disorders. Families are encouraged to seek genetic counseling to discuss recurrence risks, which, assuming an autosomal recessive inheritance, typically suggests a 25% chance for each subsequent pregnancy.

How do families manage the daily challenges of Dubowitz syndrome?

Living with Dubowitz syndrome requires a multidisciplinary approach to care. Because the condition affects multiple systems, management usually involves a team including pediatricians, neurologists, gastroenterologists, and speech and physical therapists. Emotional support is equally vital; the uncertainty regarding the molecular cause of Dubowitz syndrome can be difficult for caregivers. Engaging with communities like the one at DiseaseMaps.org can provide invaluable peer support and shared strategies for navigating the complexities of rare disease healthcare.

Next steps

• Consult a Clinical Geneticist: If you suspect a diagnosis, request a referral to a geneticist to discuss the latest diagnostic testing options.


• Coordinate Multidisciplinary Care: Ensure your primary care physician acts as a hub to coordinate between specialists managing the growth, neurological, and feeding needs of the patient.


• Join a Support Network: Connect with the six individuals on DiseaseMaps.org who are managing Dubowitz syndrome to share experiences and coping strategies.


• Monitor Developments: Stay updated on emerging research by checking the NIH GARD portal regularly for any new genetic associations linked to Dubowitz syndrome.
