Hereditary Amyloidosis
- Autosomal dominant
Hereditary amyloidosis refers to a group of inherited conditions that make up one of the subtypes of amyloidosis. Hereditary amyloidosisis characterized by the deposit of an abnormal protein called amyloid in multiple organs of the body where it should not be, which causes disruption of organ tissue structure and function. In hereditary amyloidosis, amyloid deposits most often occur in tissues of the heart, kidneys, and nervous system. While symptoms of hereditary amyloidosis may appear in childhood, most individuals do not experience symptoms until adulthood. There are many types of hereditary amyloidosis associated with different gene mutations and abnormal proteins. The most common type of hereditary amyloidosis is transthyretin amyloidosis (ATTR), a condition in which the amyloid deposits are most often made up of the transthyretin protein which is made in the liver. Other examplesof hereditary amyloidosis include, but are not limited to, apolipoprotein AI amyloidosis (A ApoAI), gelsolin amyloidosis (A Gel), lysozyme amyloidosis (A Lys), cystatin C amyloidosis (A Cys), fibrinogen Aα-chain amyloidosis (A Fib), and apolipoprotein AII amyloidosis (A ApoAII).

Hereditary Corneal Dystrophies
- Corneal Dystrophy
A group of inherited conditions affecting one or more layers of the cornea, including Fuchs endothelial dystrophy (often linked to a TCF4 repeat expansion), TGFBI-related granular and lattice dystrophies, and rarer types caused by genes such as SLC4A11, COL8A2, ZEB1 and CHST6.
- 3 GenCC submitters rate it definitive or strong
What knowing changes
Carriers of TGFBI variants are generally advised to avoid laser refractive surgery (LASIK or PRK), which can make deposits worse; corneal transplant can restore vision in advanced disease.
Inheritance
- Autosomal dominant
- One changed copy, from either parent, is enough. A parent who has one passes it on to each child with a one-in-two chance.

- Known disease-causing sites
- Stretches short reads find hard
Exons of the gene's MANE Select transcript (release v1.5), from NCBI and EMBL-EBI, on the GRCh38 reference genome.
Chromosome bands from UCSC's GRCh38 ideogram (2022-10-29).
Nearby genes from Ensembl release 116, on GRCh38.
Exons make up 2.6 kb of the gene's 64.7 kb; 2,196 of those bases code for the protein.

None of them falls in a region short reads find hard.
A whole genome covers all 64.7 kb of GSN, introns included, not only the 2.6 kb of exons.
