Musical aptitude

From SNPedia

Hereditary basis of musical aptitude and creativity has been strongly suspected at least since the days of Bach family, which in eight generations produced over twenty eminent musicians. Analysis of such complex trait poses numerous problems, however. Not the least of them is having everyone agree on a definition of the phenotype. One such approach measures aptitude by Karma Music Test KMT (Heritability 46%) and Carl Seashore's subtests of pitch SP (Heritability 68%) and time discrimination ST (Heritability 21%) as well as their combination COMB (Heritability 60%).

The study [PMID 24614497] identifies 28+ SNP's "maybe" linked to musical aptitude, but doesn't give the associated alleles or magnitude, making the data at this point mostly useful for tracking heredity. The presentation of the results is perhaps little unusual, though it's in a series of incremental studies on the subject. To avoid filling SNPedia with related SNP's as most of the associations seem fairly tenuous, the less associated ones are listed here. The probabilities are in posterior probability of linkage (PPL) or posterior probability of LD (PPLD) for regions. See the actual study and supplementary materials for details.

Not listing pedigree-wise linkage SNP's as the sample set for those is quite small per pedigree. There is also a specific haplotype probability table centered on rs3803.
