- Developmental Delay
Keywords: Congenital cataract, developmental delay, Warburg micro syndrome Introduction Warburg micro syndrome is a rare autosomal recessive genetic disorder characterized by microcephaly, microcornea, congenital cataract, developmental delay, and hypogonadism [ncbi.nlm.nih.gov]
As the child grows, puberty is delayed due to hypogonadism which is a part of this syndrome. This report aims to generate awareness regarding this rare cause of bilateral congenital cataract with developmental delay. [pediatricneurosciences.com]
DOI: 10.19080/AJPN.2020.09.555816 Abstract Six months old child brought to our attention for developmental delay. Child came to our hospital for measles, on detailed history and examination, developmental delay noted at 6 months of age. [juniperpublishers.com]

- Malnutrition
Feeding problems and malnutrition are present in most of the children due to their physical and mental disability. As the child grows, puberty is delayed due to hypogonadism which is a part of this syndrome. [ncbi.nlm.nih.gov]
Gastrointestinal
- Failure to Thrive
The diagnosis of this syndrome is based on clinical grounds, but there are certain syndromes similar to Warburg syndrome, these are CAMFAK syndrome (cataract, arthrogryposis, microcephaly, failure to thrive, and kyphoscoliosis) [6], CAMAK syndrome (cataract [juniperpublishers.com]

The patients also present with dysmorphic features, such as beaked nose with a prominent nasal root, large anteverted ears, hypertrichosis, micrognathia, and highly arched palate. Seizures and/or limb contractures may develop in some patients. [cags.org.ae]
Abnormal craniofacial features in the proband include deep-set eyes, a prominent nasal bridge and root, a maxillary protrusion, and large anteverted ears. [nature.com]
Facial features include a prominent nasal root, relatively short nose and large ears. His weight was normal 8.4 kg. Furthermore, he had motor milestones and language delay, optic atrophy and visual impairment with no seizures. [academic.oup.com]

Psychiatrical
- Psychomotor Retardation
Some degree of psychomotor retardation and developmental delays is common. Both spasticity and hypotonia have been described. Some patients have seizures. Facial hypertrichosis, anteverted ears, and a broad nasal bridge are often noted. [disorders.eyes.arizona.edu]

Rodriguez Criado et al. (1999) discussed Micro syndrome in 2 sisters with microcephaly, microphthalmia, microcorneas, cataracts, sparse medial eyebrows, micrognathia, and severe psychomotor retardation. The parents were not related in this family. [iamg.in]
Neurologic
- Quadriplegia
In Warburg micro syndrome, a progressive ascending spastic paraplegia typically begins with spastic diplegia and contractures during the first year, followed by upper-limb involvement leading to spastic quadriplegia after about age five years, often eventually [ncbi.nlm.nih.gov]
The older children were wheelchair bound and had kyphoscoliosis, severe spastic quadriplegia with contractures, and diminished muscle bulk. [bio2rdf.org]
The muscle problems worsen (progress) to include the arms and lead to paralysis of all four limbs (spastic quadriplegia). Eventually, breathing may be impaired. The brain abnormalities can contribute to vision problems (cortical visual impairment). [medlineplus.gov]

Urogenital
- Microphallus
He had microphallus, scrotal hypoplasia and atrophic testes. He had axial hypotonia and the deep tendon reflexes were brisk. There was no organomegaly. His fingers were long and thin. [iamg.in]
Workup
Clinical Testing and Workup A thorough eye (ophthalmological) examination is necessary in infants suspected of Warburg Micro syndrome. Such an exam can reveal characteristic changes in the eyes. [rarediseases.org]
Treatment
PMID 26063829. ^ "Are There Treatments for Warburg Micro." https://www.warburgmicro.org/treatment/ 27 Mar. 2022. [en.wikipedia.org]
Treatment Treatment Options: No effective treatment is available. Vision remains subnormal even after cataracts are removed. Nutrition may be improved with placement of a gastrostomy tube. [disorders.eyes.arizona.edu]
Treatment is symptomatic. Since congenital cataract is the most common symptom of the disease, most treatment strategies would target it. [cags.org.ae]
Prognosis

The overall prognosis is poor with most infants dying within the 1st year of life. [radiopaedia.org]

Etiology
Symptomatic treatment is not always recommended, and in fact, it may be dangerous, because it may mask the presence of an underlying etiology which will then be forgotten or treated with great delay. [en.wikipedia.org]
Etiology Mutations in RAB3GAP, a gene showing linkage to a region of homozygosity at 2q21.3, have been identified in some families. [rarediseases.info.nih.gov]
They are organised into groups, and further divided into clinical, etiological or histopathological sub-types. [orpha.net]
