|March 1, 1976
Summary
This study reports on monozygotic twins with cerebral gigantism, noting characteristic brain imaging, dermatoglyphic patterns, and growth hormone levels. These findings contribute to understanding this rare genetic disorder.
Area of Science:
- Pediatric Endocrinology
- Clinical Genetics
- Neuroimaging
Background:
- Cerebral gigantism, also known as Sotos syndrome, is a rare genetic disorder characterized by excessive growth in childhood.
- Early diagnosis and understanding of its features are crucial for management.
Observation:
- The study details two cases of likely monozygotic twins presenting with cerebral gigantism.
- Key clinical observations included specific neuroimaging and dermatoglyphic findings.
Findings:
- Pneumoencephalography revealed anterior ventricular dilatation in both twins.
- Dermatoglyphic analysis showed a unique pattern: a thenar exit of the A-line and vertical palmar alignment.
- Blood concentrations of growth hormone and sulfation factor were low, yet within normal physiological ranges.
Implications:
- These findings highlight specific diagnostic markers for cerebral gigantism in twins.
- Further research can elucidate the genetic and hormonal underpinnings of this condition.
- Understanding these features aids in accurate diagnosis and potential therapeutic strategies.

01:18Polygenic Traits
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...
01:33Pleiotropy
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,...
01:10Nature and Nurture
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...

There are many research methods available to psychologists in their efforts to understand, describe, and explain behavior and the cognitive and biological processes that underlie it.
02:30Genomic Imprinting and Inheritance
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...

01:27Goiter
Goiter refers to an abnormal enlargement of the thyroid gland that may appear as a diffuse goiter (uniform enlargement) or nodular (single or multiple nodules). Functionally, it is classified as nontoxic (normal/low hormone levels) or toxic (excess hormone production).PathophysiologyDiffuse thyroid enlargement typically results from prolonged stimulation by thyroid-stimulating hormone (TSH) or TSH-like agents, commonly seen in hypothyroidism or iodine deficiency. In contrast, in hyperthyroid...
