PIEZO1-gene gain-of-function mutations with lower limb lymphedema onset in an adult: Clinical, scintigraphic, and noncontrast magnetic resonance lymphography findings.

Am J Med Genet A 2021 Sep 3. Epub 2021 Sep 3.

Service d'Hématologie Biologique, APHP, CHU Bicêtre, Le Kremlin-Bicêtre, France.

Primary lymphedema, a rare disease, has a genetic cause in ~40% of patients. Recently, loss-of-function mutations in PIEZO1, which encodes the mechanotransducer protein PIEZO1, were described as causing primary lymphedema, when gain-of-function PIEZO1 mutations were attributed to dehydrated hereditary stomatocytosis type-1 (DHS), a dominant red cell hemolytic disorder, with ~20% of patients having perinatal edema. Lymphedema was diagnosed in a 36-year-old man from a three-generation DHS family, with a PIEZO1-allele harboring 3 missense mutations in cis. Read More

Neonatal Renal Failure in the Setting of Anorectal Malformation: A Case Report and Literature Review.

Cureus 2021 May 12;13(5):e14984. Epub 2021 May 12.

Pediatric Surgery, University of Missouri Kansas City School of Medicine, Kansas City, USA.

Anorectal malformations (ARMs) can occur in isolation or in association with other anomalies, most commonly those of the genitourinary systems. Morbidity and mortality are highest among patients who develop end-stage renal disease (ESRD) either from severe congenital anomalies (dysplastic kidneys) or from repeated infections in those who have vesicoureteral reflux or persistent recto-urinary fistulas. We describe our management strategy for a patient born with an ARM and bilateral dysplastic kidneys to highlight the nuances and complex decision-making considerations required in taking care of this complex patient population.
