Nature and Nurture

Nature 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...

Polygenic Traits

Polygenic 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...

Signs of Puberty

Signs of Puberty

Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

Sex Linked Disorders

Sex Linked Disorders

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

Heritability

Heritability

Heritability is a statistical concept that measures the degree to which genetic differences among individuals contribute to trait variations within a population. It is a fundamental idea in genetics, often prone to misinterpretation. Heritability is expressed as a percentage, reflecting the proportion of variation in a specific trait across a population that can be linked to genetic differences. However, it's important to understand that heritability does not determine how "genetic" a trait is,...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Summary

Short stature in children is defined as height below -2 standard deviation scores. Idiopathic short stature, a common form, requires excluding other causes before considering growth hormone therapy for improved outcomes.

Area of Science:

Pediatric Endocrinology
Genetics
Child Development

Context:

Childhood growth monitoring is crucial for identifying physiological and pathological events.
Short stature is statistically defined as height below -2 standard deviation scores or the third percentile for age and sex.
Molecular genetics advances aid in diagnosing endocrine disorders.

Purpose:

To define idiopathic short stature (ISS) and its diagnostic criteria.
To outline the exclusion process for other causes of short stature.
To establish the role of growth hormone (GH) therapy in ISS.

Summary:

Idiopathic short stature (ISS) is a heterogeneous condition of unknown etiology, excluding specific causes like GH deficiency, Turner syndrome, or chronic diseases.

ISS is characterized by normal birth measurements, normal GH response to stimulation tests, and height SDS rates between -2 and -3.

Criteria for initiating GH therapy in ISS include SDS rates <-2.25 or <1.2 percentile, aiming for normal adult height.

Impact:

Accurate diagnosis of ISS is essential for appropriate management and intervention.
Growth hormone therapy can help children with ISS achieve normal height and improve psychosocial well-being.
Understanding the genetic and endocrine factors in ISS can lead to improved diagnostic tools and treatments.
