    ### Response:
    What are the signs and symptoms of Omenn syndrome? Infants with Omenn syndrome typically present shortly after birth, usually by 3 months of age. This is similar to other types of severe combined immunodeficiency (SCID). The characteristic skin findings (red and peeling skin), chronic diarrhea, and failure to thrive often precede the onset of infections.
