Summary
Costello syndrome (CS) is a rare genetic disorder. Our study identifies a specific HRAS gene mutation (G12S) in Dutch patients, suggesting genetic homogeneity for this condition.
Area of Science:
- Genetics
- Molecular Biology
- Medical Science
Background:
- Costello syndrome (CS) is a rare genetic disorder characterized by multiple congenital anomalies, developmental delays, and specific physical features.
- CS is associated with an increased risk of both benign and malignant tumors.
- Previous research indicates that CS is caused by recurrent mutations in the HRAS gene.
Observation:
- This study analyzed three unrelated Dutch patients diagnosed with Costello syndrome.
- Genetic analysis revealed a consistent G12S mutation in the HRAS gene across all three patients.
- This represents the first genetic analysis of Costello syndrome in Dutch patients.
Findings:
- The identified G12S mutation in the HRAS gene is a recurring cause of Costello syndrome.
- The genetic homogeneity observed in this Dutch cohort suggests a common mutational basis.
- The findings reinforce the role of HRAS gene mutations in the etiology of CS.
Implications:
- These findings contribute to a better understanding of the genetic underpinnings of Costello syndrome.
- Identifying specific mutations can aid in genetic counseling and diagnosis for families affected by CS.
- Further research into HRAS mutations may reveal new therapeutic targets for Costello syndrome and related disorders.

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,...
01:31Translation
Lesson: Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.

02:08Gene Conversion
Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...
02:18Alternative RNA Splicing
Alternative RNA splicing is the regulated splicing of exons and introns to produce different mature mRNAs from a single pre-mRNA. Unlike in constitutive splicing where a single gene produces a single type of mRNA, alternative splicing allows an organism to produce multiple proteins from a single gene and plays an important role in protein diversity.
There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...

01:21Huntington Disease l: Introduction
Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
