芬蘭赫爾辛基大學(xué)和西貝柳斯音樂學(xué)院研究人員的一項最新研究成果表明,，人類的音樂天賦具有很強的遺傳性。
當(dāng)?shù)孛襟w23日報道說,，芬蘭研究人員選擇來自31個芬蘭家族的400名音樂家,、業(yè)余愛好者和未受過音樂訓(xùn)練的人為研究對象，通過聽覺構(gòu)建能力測試,、西肖爾音高分辨和時間辨別測試等評估受試者的音樂才能,。此外，研究人員還采集了12歲以上受試者的血樣,。
結(jié)果發(fā)現(xiàn),，在芬蘭音樂世家的音樂才能中，約有50%可解釋為基因因素,。研究人員說,，這是首次在分子遺傳學(xué)層面揭示音樂天賦的遺傳性。（生物谷Bioon.com）

Association of the arginine vasopressin receptor 1A (AVPR1A) haplotypes with listening to music

AbstractMusic is listened in all cultures. We hypothesize that willingness to produce and perceive sound and music is social communication that needs musical aptitude. Here, listening to music was surveyed using a web-based questionnaire and musical aptitude using the auditory structuring ability test (Karma Music test) and Carl Seashores tests for pitch and for time. Three highly polymorphic microsatellite markers (RS3, RS1 and AVR) of the arginine vasopressin receptor 1A (AVPR1A) gene, previously associated with social communication and attachment, were genotyped and analyzed in 31 Finnish families (n=437 members) using family-based association analysis. A positive association between the AVPR1A haplotype (RS1 and AVR) and active current listening to music (permuted P=0.0019) was observed. Other AVPR1A haplotype (RS3 and AVR) showed association with lifelong active listening to music (permuted P=0.0022). In addition to AVPR1A, two polymorphisms (5-HTTLPR and variable number of tandem repeat) of human serotonin transporter gene (SLC6A4), a candidate gene for many neuropsychiatric disorders and previously associated with emotional processing, were analyzed. No association between listening to music and the polymorphisms of SLC6A4 were detected. The results suggest that willingness to listen to music is related to neurobiological pathways affecting social affiliation and communication.
