Detection of MLPH gene polymorphism in population of the Belgian Shepherd variety Malinois ; Detekcia polymorfizmu génu MLPH v populácii belgického ovčiaka variety malinois
Melanophilin (MLPH) gene affects dilution of coat colour. It focuses on D locus alleles and in c.-22G>A polymorphism 2 alleles were described. Dominant D allele controls regular colour whereas recessive d allele causes dilution. Diluted colouration in Belgian Shepherd variety Malinois is undesirable and excluded from breeding. Dilution of the coat colour can sometimes be accompanied by skin disease (CDA or BHFD). Methods of molecular genetics including PCR-RFLP method were used to identify c.-22G>A polymorphism in MLPH gene. Within the analysed population of 56 dogs following genotypes w... Mehr ...

Melanophilin (MLPH) gene affects dilution of coat colour. It focuses on D locus alleles and in c.-22G>A polymorphism 2 alleles were described. Dominant D allele controls regular colour whereas recessive d allele causes dilution. Diluted colouration in Belgian Shepherd variety Malinois is undesirable and excluded from breeding. Dilution of the coat colour can sometimes be accompanied by skin disease (CDA or BHFD). Methods of molecular genetics including PCR-RFLP method were used to identify c.-22G>A polymorphism in MLPH gene. Within the analysed population of 56 dogs following genotypes were discovered: 50 dogs with homozygous DD genotype, i.e. 89.29% frequency of occurrence and 6 dogs with heterozygous Dd genotype, i.e. 10.71% frequency of occurrence. ; Gén melanofilín (MLPH) je zodpovedný za zriedenie farby srsti. Jedná sa o sériu alel D lokusu, pričom pre polymorfizmus c.-22G>A boli popísané 2 alely. Dominantná alela D kontroluje normálne sfarbenie srsti a recesívna alela d je zodpovedná za zriedenie. Zriedené sfarbenie je u belgického ovčiaka variety Malinois nežiaduce a vyraďujúce z chovu. Zriedenie farby srsti môže byť niekedy sprevádzané ochorením kože (CDA alebo BHFD). Pomocou molekulárno-genetických metód s využitím PCR-RFLP metódy prebehla identifikácia polymorfizmu c.-22G>A v géne MLPH. V sledovanej populácii 56 psov boli zistené tieto genotypy: 50 psov s homozygotným genotypom DD, čo predstavuje frekvenciu výskytu 89,29 % a 6 psov s heterozygotným genotypom Dd, čo zodpovedá frekvencii výskytu 10,71 %.
