Overview
The exact pathogenesis of [disease name] is not fully understood.
OR
It is thought that [disease name] is the result of / is mediated by / is produced by / is caused by either [hypothesis 1], [hypothesis 2], or [hypothesis 3].
OR
[Pathogen name] is usually transmitted via the [transmission route] route to the human host.
OR
Following transmission/ingestion, the [pathogen] uses the [entry site] to invade the [cell name] cell.
OR
[Disease or malignancy name] arises from [cell name]s, which are [cell type] cells that are normally involved in [function of cells].
OR
The progression to [disease name] usually involves the [molecular pathway].
OR
The pathophysiology of [disease/malignancy] depends on the histological subtype.
Pathophysiology
Pathogenesis
- It is understood that amyloidosis is the result of deposition of Amyloid.[1]
- Amyloid is an abnormal insoluble extracellular protein which may cause organic dysfunction and a wide variety of clinical syndromes.
- These abnormal amyloids are derived from misfolding and aggregation of normally soluble proteins.
- Amyloid deposition can disrupt tissue structure of involved organ and consequently leads to organ failure.[2]
Genetics
- Familial ATTR amyloidosis is transmitted in autosomal dominant pattern but it can have a heterogeneous nature of presentation.[3][4][5]
- Genes involved in the pathogenesis of Familial ATTR amyloidosis include:
Associated Conditions
Conditions associated with [disease name] include:
- [Condition 1]
- [Condition 2]
- [Condition 3]
Gross Pathology
On gross pathology, [feature1], [feature2], and [feature3] are characteristic findings of [disease name].
Microscopic Pathology
On microscopic histopathological analysis, [feature1], [feature2], and [feature3] are characteristic findings of [disease name].
