Insights

Fibroblast growth factor receptor 2 (FGFR2) gene mutations cause craniosynostosis syndromes. A novel S267P mutation in FGFR2 was identified in a patient with Crouzon syndrome, expanding the known genetic causes.

Area of Science:

  • Genetics
  • Molecular Biology
  • Developmental Biology

Background:

  • Syndromic craniosynostosis, including Apert, Crouzon, and Pfeiffer syndromes, are known to be caused by mutations in the fibroblast growth factor receptor 2 (FGFR2) gene.
  • FGFR2 mutations lead to premature fusion of cranial sutures, impacting skull development.

Observation:

  • A patient clinically diagnosed with Crouzon syndrome was analyzed for genetic mutations.
  • The study focused on identifying specific genetic alterations within the FGFR2 gene in this patient.

Findings:

  • A novel missense point mutation, S267P, was identified in the FGFR2 gene of the Crouzon syndrome patient.
  • This S267P mutation is reported for the first time in association with Crouzon syndrome.

Implications:

  • The discovery of the S267P mutation expands the known molecular spectrum of FGFR2 mutations in Crouzon syndrome.
  • This finding contributes to a better understanding of the genetic heterogeneity underlying syndromic craniosynostosis.
  • Further research may elucidate the specific pathogenic mechanisms of this novel FGFR2 mutation.

Cystic Fibrosis: Pathogenesis

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Pleiotropy01:33

Pleiotropy

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,...

Alternative RNA Splicing02:18

Alternative 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...

Point and Frameshift Mutations01:30

Point and Frameshift Mutations

Point mutations are genetic alterations involving the change of a single nucleotide base pair in DNA. Depending on how the alteration affects protein synthesis, they can lead to various consequences.Point mutations fall into the following types:Silent mutations occur when a nucleotide change does not alter the amino acid sequence due to the redundancy of the genetic code. For instance, changing ACC to ACA still encodes threonine, leaving the protein function unaffected. This occurs because...

Cis-regulatory Sequences02:02

Cis-regulatory Sequences

Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

Incomplete Dominance01:43

Incomplete Dominance

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.
