TRIP13

Chr 5AR

thyroid hormone receptor interactor 13

Also known as: 16E1BP, MVA3, OOMD9, OZEMA9

TRIP13 encodes a protein essential for chromosome recombination, synaptonemal complex formation during meiosis, and mitotic spindle assembly checkpoint activation. Mutations cause mosaic variegated aneuploidy syndrome and oocyte/zygote/embryo maturation arrest with autosomal recessive inheritance. The gene is highly constrained against loss-of-function variants (pLI 1.0, LOEUF 0.25), reflecting its critical role in chromosome stability and reproductive function.

Clinical SummaryTRIP13
Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 1.00). One damaged copy is likely sufficient to cause disease.
