Brief Summary
Fabry disease is caused by the deficiency or absence of alpha-galactosidase A (α-Gal A) activity, leading to progressive deposition of glycosphingolipids, mainly globotriaosylceramide (Gb3), in the lysosomes of multiple tissues and organs. In Taiwan, Dr. Niu first revealed a surprisingly high incidence (approximately one in 1,600 males) of a cardiac variant GLA splicing mutation, IVS4+919G\>A, in newborn screening. Patients who carried the IVS4 + 919G \> A mutation and were older than 40 years had a higher prevalence of hypertrophic cardiomyopathy. Endocardial biopsy of these patients with hypertrophic cardiomyopathy showed significant Gb3 accumulation in the cardiomyocytes. Although the hotspot IVS4+919G\>A mutation is now being observed with greater frequency, understanding of the natural course of cardiac variant Fabry disease with this specific mutation remains limited. Therefore, our study would like to conduct a study to approach the natural history among patients with Chinese hotspot late-onset Fabry mutation IVS4+919G\>A through family pedigree analysis.

Outcome Measures
Primary Outcomes (1)
Completeness of IVS4 family tree mapping and obligate carrier identification within their family pedigree
First patient in : 30-Sep-2017; Last Patient out : 1-June-2020
Interventions
1. Enroll first generation (newborn), at least one member from second (parent) and third generation (grandparent) for a complete IVS4 family tree mapping. 2. Collect and analyze medical history, genetic and biochemical assessment data
Eligibility Criteria
This prospective family screening study aim to enrol family members from pre-identified IVS4 female newborn's family. IVS4 female newborn's family member will be invited to join the family screening study with written informed consent prior to any specific study procedure. After written informed consent process, a series of screening examination will be conducted at screening visit which included medical history interview, physical examination, α-Gal A enzyme activity test, genetic test, plasma lyso-GB3, renal function and cardiac function assessment as well as pedigree data analysis for IVS4 family tree mapping.
You may qualify if:
- Fabry IVS4 female newborn family members.
- Patients and/or their legal representatives who are willing to provide written informed consent
You may not qualify if:
- No blood relatives to the IVS4 female newborn family
