Case#: 34 year-old Chinese male.

DiseaseAssertion: HAE-C1INH Type 1.

FamilyInfo: Family history of edema (mother passed away due to laryngeal edema, older sister experienced buttock swelling after prolonged sitting, maternal uncle experienced episodic abdominal pain and unilateral upper-limb swelling). Family testing for serum C4 and C1INH concentration and C1INH functional activity indicate that proband’s maternal uncle and asymptomatic daughter exhibit low values for all three of these biochemical markers, consistent with Type 1 HAE. The proband’s daughter and maternal uncle also tested positive for the variant identified in the proband. Pedigree included in figures.

ParentalTesting: Mother passed away before study. Father tested for C4 and C1INH concentration and C1INH function with all values falling in normal ranges.

CasePresentingHPOs: Edema (HP:0000969), Edema of the dorsum of hands (HP:0007514), Edema of the upper limbs (HP:0010742), Non-pitting edema (HP:6000507), Abdominal pain (HP:0002027)

CasePhenotypeFreeText: Onset at approximate age of 26. Episodes of localized edema of limbs, skin, and buttocks lasting two to three days regardless of treatment. Episodes became more frequent at age 34 and were accompanied by abdominal pain triggered by fatigue. Non-pitting edema of right hand observed on physical examination.. The proband’s C4 level was 0.02 g/L (reference range: 0.1–0.4 g/L), C1INH concentration was 0.07 g/L (reference range: 0.21–0.39 g/L), and C1INH functional activity was 4.3% (reference range: ≥68.0%).

-Gene: DICER1 -PMID: 29343557 -Inheritance Pattern: DICER1 is inherited as an autosomal dominant condition with decreased penetrance -Disease Entity: earlier onset disease, multisite disease, 0-2 site disease, cystic lung disease, familial disease, bilateral disease, stage IA/IB, bilateral disease -mutation: germline loss-of-function mutation, missense mutation, Intronic mutations, hotspot mutation, second somatic mutation, truncating mutations, biallelic mutation -zygosity: heterozygosity -Family History: -testing should be considered for those with a family history of DICER1-associated conditions so that appropriate surveillance can be undertaken. -Individuals at 50% risk of a germline pathogenic variant based on family history who do not pursue genetic testing should follow surveillance guidelines as -if they have a DICER1 mutation unless/until genetic testing confirms that they did not inherit the familial mutation When a pulmonary cyst is identified in a young child with a pathogenic germline -DICER1 variant or family history of a DICER1-associated condition, it should be assumed to be Type I PPB until proven otherwise

Other Information: -Case: Risk for most DICER1-associated neoplasms is highest in early childhood and decreases in adulthood -affected phenotype may simply result from probabilities of generating the characteristic “loss-of-function plus hotspot” two hit typical of a DICER1 syndrome neoplasm. -Caseprevioustesting: presymptomatic testing of a minor child, should be discussed and factored into the decision process, as some individuals may choose, and have the right to choose, not to know their/their child’s genetic status. -gnomAD: n/a
