Tuberous Sclerosis Complex and Lymphangioleiomyomatosis Pregnancy Registry (TSC-LAM Registry)

January 21, 2026 updated by: David M. Ritter

Tuberous Sclerosis Complex and Lymphangioleiomyomatosis Pregnancy Registry

This study is an observational registry designed to gather information about Tuberous Sclerosis Complex (TSC) and Lymphangioleiomyomatosis (LAM) in pregnant women and their child.

Study Overview

Detailed Description

Tuberous sclerosis complex (TSC) is caused by mutations in tuberous sclerosis complex 1 (TSC 1) and tuberous sclerosis complex 2 (TSC 2) leading to overactivation of the mammilian target of rapamycin (mTOR) pathway resulting in multiorgan disease. Specifically, patients are at risk for autism, epilepsy, intellectual disability, renal cysts, tuberous sclerosis associated neuropsychiatric disorder (TAND), lymphangioleiomyomatosis (LAM), and benign tumors throughout the body including subependymal giant cell astrocytomas (SEGAs), renal and liver angiomyolipomas (AMLs), and cardiac rhabdomyomas (rhabdomyomas).

Sporadic LAM occurs mostly in women and many patients with LAM have TSC gene mutations.

The purpose of this study is to gather information to help clinicians develop evidence-based guidance for the care of TSC and LAM patients during pregnancy and to provide screening recommendations for fetal TSC.

Participants will be asked to complete monthly online surveys screening for changes in the pregnancy, maternal health/medication changes, and other care. For infants enrolled after birth, clinical data will be collected and reviewed for up to 5 years of age.

Study Population

This registry is designed to enroll pregnant women who have a TSC and/or LAM diagnosis, a variant of uncertain significance in the TSC 1 or TSC 2 genes, whose fetus has a 50% chance of TSC as deemed by the study PI or Sub-Is, or whose fetus is found to have concern for TSC based on fetal testing.

Infants born to an enrolled individual regardless of gender and TSC status are eligible for enrollment into the registry.

Description

Inclusion Criteria:

  • A pregnant woman with a clinical or genetic diagnosis of TSC as determined by the 2021 Consensus Guidelines (1)
  • A pregnant woman with a diagnosis of LAM
  • A pregnant woman with a variant of uncertain significance in TSC 1 or TSC 2
  • A pregnant woman who is pregnant and the fetus has a 50% chance of TSC as deemed by the PI or Sub-Is
  • A pregnant woman whose fetus is found to have concern for TSC secondary to rhabdomyomas, tubers, or congenital subependymal giant cell astrocytoma.
  • An infant born to an enrolled individual.

Exclusion Criteria:

  • A pregnant woman without TSC who has used preimplantation genetic testing for TSC unless qualifies under inclusion criteria #4.
  • Infants diagnosed with TSC whose birth mother was not enrolled.

During pregnancy (up to 40 weeks) through 6 months post-delivery
Maternal-Fetal Complications in TSC
Time Frame: During pregnancy (up to 40 weeks)
Screening for changes in pregnancy, maternal health/medication changes and other care by using a study-developed monthly questionnaire inquiring about pregnancy status, maternal and/or fetal testing, changes to maternal and fetal care clinical providers, addition or removal of medications, changes in medication doses, and addition of new complications to mother and/or fetus using a list of common gestational complications within prior month.
During pregnancy (up to 40 weeks)
