Clarifying the immunoglobulin light chain variable gene usage in Chinese patients with renal AL amyloidosis

Key Points

Severe kidney structural damage is linked to IGLV1 gene usage, impacting renal function significantly.
Full nephrotic syndrome occurs more frequently in patients with IGLV6-57, suggesting a distinct phenotype.
Assessment highlights the connection between specific immunoglobulin genes and clinicopathological features of AL amyloidosis.
Findings indicate that IGLV1-51 usage may serve as a predictor of poor renal survival, warranting further investigation.

Abstract

The IGVL gene usage is associated with distinct clinicopathological features in renal AL amyloidosis, IGLV6-57 is linked to a higher frequency of full nephrotic syndrome, IGKV1 is associated with severe kidney structural damage and hepatic tropism, and IGLV1-51 potentially predicts poor renal survival.
