Also known as: BOAT, BOAT1

ATXN1L encodes a chromatin-binding protein that represses Notch signaling and is involved in brain development. The gene is highly constrained against loss-of-function variants (pLI 0.98, LOEUF 0.31), but no specific disease phenotypes have been definitively established for ATXN1L mutations in humans.

Clinical SummaryATXN1L
Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 0.98). One damaged copy is likely sufficient to cause disease.
