Smith-Lemli-Opitz syndrome is a genetic condition that is present from conception, but signs may occasionally be so subtle that patients avoid detection until later childhood or even adulthood. Some have postulated that the mildest cases may completely escape detection in some instances. More commonly, Smith-Lemli-Opitz syndrome is suspected at birth or shortly thereafter because of birth defects.
