Junctophilin-1 is a modifier gene of GDAP1-related Charcot-Marie-Tooth disease.
The authors found MEFV as a susceptibility and modifier gene in BD.
Such modifier gene identification was described for polycystic kidney disease using [kat.sup.2J] (kat: kidney, anemia, and testes phenotype) mutant mice [21] and multiple intestinal neoplasia using min (multiple intestinal neoplasia) mutant mice [22].
Because each set of iPSCs is specific to the individual from whom they arc derived, researchers can compare the sets to identify molecular differences, such as a modifier gene active in one person but not the other.
Considering all data, human homologous of Bop gene (BOP) seems to be candidate modifier gene for HCMP in which both cardiac hypertrophy and cardiac contraction have central role.
A genome-wide scan carried out by Bykhovskaya et al (96) using parametric analysis of the Arab-Israeli family failed to identify a single major nuclear modifier gene. However, they reported a candidate locus for a nuclear modifier gene associated with the mtDNA A1555G mutation in a same family using nonparametric analysis.
Indeed, when evolving populations become fixed for adaptive and ameliorative mutations, distinction between allele replacement and modifier gene occurrences is no longer possible, unless a genetic survey of the population is continuously conducted.
Because each set of iPSCs is specific to the individual from whom they are derived, researchers can compare the sets to identify molecular differences, such as a modifier gene active in one person but not the other.
Thus, this modifier gene is of a qualitatively different character than that used in the study of the evolution of recombination, mutation, or migration (Feldman 1972; Feldman et al.
The researchers also point out that previous mouse studies have implicated the modifier gene on chromosome 4 in audiogenic seizures, another form of epilepsy.
