Title: Expanding Phenotypes of Female Heterozygotes in X-Linked Neurogenetic Conditions

Sponsored by The Education and Professional Development Committee

1.0 AMA PRA Category 1 Credits™, P.A.C.E.® - Educational Credits Claim by November 21

Historically categorized as either "X-linked recessive" or "X-linked dominant," X-linked neurogenetic conditions have long been considered male-predominant. However, emerging research and clinical evidence reveal that female heterozygotes—once thought to be largely unaffected—can experience significant symptoms due to variability in X-inactivation (lyonization). This paradigm shift is reshaping how these conditions are understood, diagnosed, and managed.

Join us for a one-hour webinar exploring the evolving clinical phenotypes of females with X-linked neurogenetic disorders. Through expert-led presentations featuring clinical cases, neuroimaging, genetic insights, and updated terminology, this session will provide valuable updates for clinicians, researchers, and genetic counselors.

Featured Presentations:

• Kuntal Sen, MD, FACMG: Foundations of X-linked inheritance, lyonization, and appropriate terminology in genetics
• Andrea Gropman, MD, FACMG: Neuroimaging and clinical spectrum of Ornithine Transcarbamylase (OTC) deficiency in females
• Stephen Chrzanowski MD, PhD: Duchenne Muscular Dystrophy in female carriers and lessons from newborn screening
• Nishitha Pillai, MBBS, FACMG: Diagnosis and management of X-linked Adrenoleukodystrophy (X-ALD) in females
• Jirair Bedoyan, MD, FACMG: Phenotypic variability in PDHA1-related Pyruvate Dehydrogenase Complex deficiency

Learning Objectives

At the conclusion of this session, participants should be able to:

1. Discuss the mechanisms leading to variable penetrance and phenotype in heterozygotes with X-linked conditions.
2. Explain the different phenotypes and data from multi-modal imaging in OTC heterozygotes.
3. Summarize presentations in X-ALD females, pathophysiology, diagnostic/management strategies and emerging therapies.
4. List DMD diagnostic strategies, clinical manifestations and appropriate management in DMD heterozygote females.
5. Summarize presentations in PDHA1 females, pathophysiology, diagnostic/management strategies

Accredited Continuing Education Financial Disclosure

The American College of Medical Genetics and Genomics (ACMG) is accredited by the Accreditation Council for Continuing Medical Education (ACCME) to provide Accredited Continuing Education (ACE) for physicians. ACMG is an organization committed to improvement of patient care and general health by the incorporation of genetics and genomics into clinical practice.

ACMG has implemented the following procedures to ensure the independence of ACE activities from commercial influence/promotional bias, the Accreditation Council for Continuing Medical Education (ACCME) requires that providers (ACMG) must be able to demonstrate that: 1) everyone in a position to control the content of an ACE activity has disclosed all financial relationships that they have had in the past 24 months with ineligible* companies; 2) ACMG has implemented a mechanism to mitigate relevant financial relationships; and 3) all relevant financial relationships with ineligible companies are disclosed to the learners before the beginning of the educational activity. The learners must also be informed if no relevant financial relationships exist.
*Ineligible companies are defined as those whose primary business is producing, marketing, selling, re-selling, or distributing healthcare products used by or on patients.
