ARID3C
Chr 9AT-rich interaction domain 3C
The protein functions as a transcription factor that promotes monocyte-to-macrophage differentiation by forming a complex with NPM1 and activating genes like STAT3, STAT1, and JUNB. Mutations cause autosomal recessive severe combined immunodeficiency with microcephaly, growth retardation, and sensitivity to ionizing radiation. The gene is highly constrained against loss-of-function variation, indicating that complete loss of function is likely incompatible with normal development.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Mild missense constraint
