Ordering Recommendation

Submission of parental control samples is required for Exome Sequencing, Trio testing.  A completed “Family Member Control History for Exome Sequencing” form and completed “Informed Consent for Exome sequencing” form must be submitted for each parental/relative’s sample to aid in result interpretation for the proband’s exome and to allow for reporting of secondary findings on parents or other relatives serving as controls.

Interpretive Data

Compliance Category

Laboratory Developed Test (LDT)


Up to four family members may serve as exome sequencing controls for a proband having Exome Sequencing, Trio (2006332). Family members samples are used to aid in interpretation of the proband's exome sequencing data. Secondary findings, including pathogenic variants in genes recommended for analysis by the American College of Medical Genetics (ACMG) and other actionable secondary variants will only be reported for control individuals who complete a separate Exome Sequencing consent form. ACMG genes are only analyzed to the extent that routine exome analysis allows and single disease-causing variants in autosomal recessive ACMG genes are not reported.
