Abstract:
We studied 28 Polish hereditary fructose intolerant (HFI) patients (26 unrelated) by direct sequencing of the ALDOB coding region/splice sites. Eight different mutations were found including two novel ones (each found in two unrelated individuals): c.250delC (frameshift) and c.522 C > G (p.Y174X). The most frequent mutation c.448 G > C (p.A150P, 67% of chromosomes) was screened for in a group of 1049 randomly selected unrelated individuals. Eight (1:131) carriers were found allowing to estimate the HFI prevalence in Poland as 1:31,000.

Glucose Transporters
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
Inborn Errors of Metabolism
Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase
Incomplete Dominance

Lethal Alleles
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
