Inclusion Criteria: * The Repository will be comprised of samples from symptomatic patients, individuals reported to be their (symptomatic or asymptomatic) biologic family members, and control individuals. In this context a "symptomatic patient" is characterized as a patient whose treating physician has identified phenotypic features and/or signs of illness potentially attributable to a genetic disorder (also referred to as "Affected" or "Proband"). There will be no age, gender, race, or health restrictions for this Biorepository Study. However, since this study will be performed at children's hospitals and since genetic disorders are more likely to be present in children less than 4 months of age these cases will likely be preferentially enrolled. Preference will also be given to those who are acutely ill, suspected of a genetic condition, and for whom a diagnosis may result in change of clinical management. Exclusion Criteria: * Participants will be excluded if they are unwilling to consent to research. A patient may be determined ineligible if there is a prior diagnosis that explains their clinical presentation, if other traditional clinical genetic testing is more appropriate at the time of referral, if the clinical presentation is insufficient at the time of referral to suggest a genetic etiology, if the parents are unable or unwilling to provide permission for participation, if child protective services is involved in the case unless the child's life is in immediate danger and research holds out a prospect of direct benefit that is important to the health or well-being of the child and is available only in the context of the research in which case permission will be obtained from the party legally responsible for medical decisions.
