Genes affected
LMNB1 (HGNC:6637): (lamin B1) 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]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 19, 2022The c.16C>T (p.P6S) alteration is located in exon 1 (coding exon 1) of the LMNB1 gene. This alteration results from a C to T substitution at nucleotide position 16, causing the proline (P) at amino acid position 6 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
