ANKRD13C

Chr 1

ankyrin repeat domain 13C

Also known as: dJ677H15.3

Enables signaling receptor binding activity. Involved in protein retention in ER lumen; regulation of anoikis; and regulation of signaling receptor activity. Located in endoplasmic reticulum and perinuclear region of cytoplasm. [provided by Alliance of Genome Resources, Apr 2025]

Clinical SummaryANKRD13C
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.
