}}Region with strongest linkage for ability to discriminate pitch found in study of 767 Finnish individuals belonging in 76 families {{PMID|24614497}}, involved in [[musical aptitude]]. [[Posterior Probability of Linkage]] given as 86% to [[trait]] Carl Seashore's subtest of pitch (SP).

Located next to the region harboring the protocadherin 7 gene, [[PCDH7]] which has been suggested to play a role in cochlear and amygdaloid complexes. This [[SNP]] is in [[LIMCH1]] LIM and calponin homology domains 1 gene, which is thought to be unlikely to be responsible, probably a combination of [[SNP]]'s frequently inherited with it are involved. The study suggests [[rs13146789]] in [[PCDH7]] as one likely causal variant.
