Summary
Schimmelpenning syndrome (SS) is a rare condition involving epidermal nevi and potential systemic defects. Early recognition of epidermal nevi is crucial for identifying associated conditions in infants.
Area of Science:
- Dermatology
- Pediatric Neurology
- Medical Genetics
Background:
- Schimmelpenning syndrome (SS) is characterized by organoid nevus following Blaschko lines, often accompanied by systemic abnormalities.
- Associated defects can involve the central nervous system, eyes, bones, and other organs.
Observation:
- A 3-month-old female infant presented with congenital verrucous epidermal nevi following Blaschko lines on the trunk, face, and limb.
- The infant also had a scalp nevus and was diagnosed with an interauricular communication postnatally.
Findings:
- Skin biopsy confirmed a complete epidermal nevus.
- Extensive laboratory tests and imaging (cerebral MRI, renal ultrasound) ruled out other systemic involvement.
- The clinical presentation led to the diagnosis of Schimmelpenning syndrome.
Implications:
- This case highlights the importance of thorough investigation in infants with epidermal nevi to detect potential associated systemic conditions.
- Multidisciplinary follow-up is essential for managing patients diagnosed with Schimmelpenning syndrome.
- Early diagnosis and management can improve outcomes for children with complex genetic syndromes.

Pleiotropy
31.3K
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Genomic Imprinting and Inheritance
30.4K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Schizophrenia
1.8K
Schizophrenia, a term introduced by Swiss psychiatrist Eugen Bleuler in 1911, describes a severe psychological disorder marked by profound disruptions in attention, thought processes, language, emotion, and interpersonal relationships. The core feature of schizophrenia is psychosis — a state characterized by a fundamental detachment from reality. This disconnection manifests through distorted logic, impaired perception, and atypical behavior, severely affecting the lives of those...

Alzheimer Disease l: Introduction
38
Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...
