MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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]
PHENOTYPE: Homozygous null mice display neonatal lethality with respiratory distress, abnormal lung, craniofacial, and skeletal morphology, reduced embryo size, impaired cellular proliferation and differentiation, and abnormal nuclear morphology. [provided by MGI curators]
