Description

Description

Primary Objective

To screen for the diagnosis of light-chain amyloidosis (AL) before the onset of symptomatic disease and to develop a training set for a likelihood algorithm.

Aim 1: Creating a network to enroll patients on a collaborative study requiring marrow and blood specimens, to collect data for a training set of likelihood statistics and to plan a future validation study.

Aim 2: Validating an NGS assay that identifies IGVL genes in clonal plasma cells.

Inclusion Criteria

Inclusion Criteria
