This gene encodes one of the two B-type lamin proteins and is a component of the nuclear lamina. A duplication of this gene is associated with autosomal dominant adult-onset leukodystrophy (ADLD). Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2015]
Forensic Context
A study in mice demonstrated that the LMNB1 was upregulated in spleen leukocytes as part of a common early transcriptional response across three models of systemic inflammation and injury (trauma/hemorrhage, burn, and LPS infusion) [Brownstein et al. DOI:10.1152/physiolgenomics.00213.2005]. This upregulation was identified via microarray analysis and was associated with pathways involved in cell death, indicating its role as a molecular marker of early inflammatory leukocyte activation following diverse injuries.
