The ryanodine receptor 1
gene maps to chromosome 19q13.2 and encodes the skeletal muscle isoform of a calcium-release channel in the sarcoplasmic reticulum (RyR1) [6, 10].
Several genes are known to affect meat quality through different roles in meat quality characteristics: the ryanodine receptor 1
(RYR1) , liver fatty acid-binding protein (L-FABP) , obesity-associated (FTO) gene , melanocortin receptor type 4 (MC4R) gene [5,6], POU1F1 [7-9], and protein kinase, AMP-activated and gamma 3 non-catalytic subunit (PRKAG3) [10 -12].

Testing of the ryanodine receptor 1
gene (RYR1) whose mutation C11843T is associated with stress susceptibility and a decrease of some parameters of meat quality (FUJII et al., 1991) is important in swine breeding programs.
Six exons had low coverage in all samples examined by all methods [APOB (apolipoprotein B) exon 1, KCNH2 exon 13, KCNQ1 (potassium voltage-gated channel, KQT-like subfamily, member 1) exon 1, RYR1 (ryanodine receptor 1
[skeletal]) exon 90, SCN5A (sodium channel, voltage-gated, type V, [alpha] subunit) exon 1, TGFBR1 (transforming growth factor, [beta] receptor 1) exon 1].
