Incomplete Dominance01:43

Incomplete Dominance

32.8K
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.

Chi-square Analysis

44.9K
The chi-square test is a statistical hypothesis test. It is used to check whether there is a significant difference between an expected value and an observed value. In the context of genetics, it enables us to either accept or reject a hypothesis, based on how much the observed values deviate from the expected values.
The chi-square test was developed by Pearson in 1990.
The first step of performing a Chi-square analysis is to establish a null hypothesis, which assumes that there is no real...

Hardy-Weinberg Principle01:49

Hardy-Weinberg Principle

77.6K
Diploid organisms have two alleles of each gene, one from each parent, in their somatic cells. Therefore, each individual contributes two alleles to the gene pool of the population. The gene pool of a population is the sum of every allele of all genes within that population and has some degree of variation. Genetic variation is typically expressed as a relative frequency, which is the percentage of the total population that has a given allele, genotype or phenotype.

Mismatch Repair01:20

Mismatch Repair

7.1K
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
The Mutator Protein Family Plays a Key Role in DNA Mismatch Repair

Pleiotropy01:33

Pleiotropy

44.2K
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,...

Area of Science:

  • Genetics
  • Genomics
  • Bioinformatics

Background:

  • Human genetic variants can disrupt protein-coding genes, posing challenges for predicting phenotypic consequences.
  • Current methods for identifying haploinsufficient or essential genes are biased towards well-studied genes.

Purpose of the Study:

  • To develop an unbiased method for predicting gene haploinsufficiency.
  • To improve predictions for less-studied genes and a wider range of genetic variants.

Main Methods:

  • Derived a haploinsufficiency score using unbiased, large-scale high-throughput datasets.
  • Integrated gene co-expression and genetic variation data from over 6000 human exomes.
  • Evaluated performance against existing methods and 'gold standard' gene sets.

Main Results:

  • The new score predicts haploinsufficiency for twice as many genes as common approaches.
  • Outperformed existing methods in predicting haploinsufficiency for less-studied genes.
  • Fine-tuning on well-studied genes did not enhance predictions for less-studied genes.

Conclusions:

  • The developed haploinsufficiency score offers a more comprehensive and unbiased prediction of gene function disruption.
  • This score can prioritize gene disruptions from various genetic variants, including structural variations, indels, and single-nucleotide variants.
  • Facilitates understanding of genetic variant impact and potential disease associations.
