The Genetic Link Between Voice Pitch and ABCC9 Variants

Researchers at deCODE Genetics have discovered sequence variants in the ABCC9 gene that influence voice pitch. The study utilized speech recordings from nearly 13,000 Icelanders and corresponding genomic data to identify common ABCC9 variants associated with higher voice pitch in both men and women. Additionally, these variants were linked to higher pulse pressure, revealing intriguing connections between voice pitch and health. The study also uncovered a heritable component in vowel acoustics, enhancing our understanding of the human vocal system.
