Voice breaking timing, LIN28B marker
The age at which the voice breaks during puberty, as men recall it.
What the research found
In the cited research, the T allele at rs395962 was associated with later recalled voice breaking in the studied men.

- GT
- Middle
- TT
- Later
What the study found
In the study, each copy went with recalled age at voice breaking about 0.12 years higher on average.
- Evidence
- Genome-wide association with independent replication
- Who was studied
- Men of European ancestry (23andMe; replication in UK Biobank)
The research behind this card was done only in men, so it is part of a report requested as male.

A DNA Traits report reads this marker in your raw DNA file and shows which of the three genotypes is yours, with how common it is. It counts the copies of the studied allele; it does not measure the trait itself.

What it cannot tell you
Studied in men of European ancestry who recalled, as adults, the age their voice broke. A single marker, one of dozens linked to puberty timing in men.
