OMIA 002077-9031 : Body weight in Gallus gallus

In other species: pig , cattle

Mendelian trait/disorder: no

Mode of inheritance: Multifactorial

Considered a defect: no

Key variant known: yes

Year key variant first reported: 2016

Molecular basis: Jia et al. (2016): "a 54-bp insertion mutation in the upstream region of miR-15a-16 . . . resulted in lower miR-16 expression by introducing three novel splicing sites instead of the missing 5′ terminal splicing of mature miR-16. Elevating miR-16 significantly inhibited DF-1 chicken embryo cell proliferation, consistent with a role in suppression of cellular growth."
