  • haplotype  listen  (HA-ploh-tipe)
    A set of closely linked genetic markers present on one chromosome which tend to be inherited together.

  • heteroduplex analysis  listen  (HEH-teh-roh-DOO-plex uh-NA-lih-sis)
    A method of detecting sequence differences between normal DNA and the DNA to be tested. It is commonly used as a screening method to detect potential mutations in a gene.

  • heterogeneity logarithm of the odds score  (HEH-teh-roh-jeh-NEE-ih-tee LAW-guh-RIH-thum … skor)
    A statistical estimate of whether two genetic loci are physically near enough to each other (or “linked”) on a particular chromosome that they are likely to be inherited together. A heterogeneity logarithm of the odds score is calculated in the presence of locus heterogeneity (when the same phenotype can be caused by mutations in genes at different chromosomal loci). Also called HLOD score.

  • heterozygous genotype  listen  (HEH-teh-roh-ZY-gus JEE-noh-tipe)
    Occurs when the two alleles at a particular gene locus are different. A heterozygous genotype may include one normal allele and one mutation, or two different mutations. The latter is called a compound heterozygote.

  • HLOD score  (... skor)
    A statistical estimate of whether two genetic loci are physically near enough to each other (or “linked”) on a particular chromosome that they are likely to be inherited together. An HLOD score is calculated in the presence of locus heterogeneity (when the same phenotype can be caused by mutations in genes at different chromosomal loci). Also called heterogeneity logarithm of the odds score.

  • homozygous genotype  listen  (HOH-moh-ZY-gus JEE-noh-tipe)
    Occurs when both alleles at a particular gene locus are the same. A person may be homozygous for the normal allele or for a mutation.
