Adult onset leukodystrophy v2.44 | LAMB1 |
Sarah Leigh edited their review of gene: LAMB1: Added comment: PMID: 34606115 reports heterozygous end-truncated LAMB1 in a hippocampal memory defect and a leukoencephalopathy. Other publications (PMID: 32548278; 25925986;23472759;29888467), OMIM (https://www.omim.org/entry/150240?search=LAMB1&highlight=lamb1#geneMap), Gen2Phen (https://www.ebi.ac.uk/gene2phenotype/gfd?dbID=1439) and ClinGen (https://search.clinicalgenome.org/kb/genes/HGNC:6486) all report the a bialleic mode inheritance between LAMB1 variants and disease. Based on this discrepancy, the suggested mode of inheritance has been changed to BOTH monoallelic and biallelic, autosomal or pseudoautosomal.; Changed mode of inheritance: BOTH monoallelic and biallelic, autosomal or pseudoautosomal |

Zornitza Stark changed review comment from: Mono-allelic LAMB1 variants reported in 5 families with cerebral small vessel disease. 4 are truncating frameshifts (and 2 of the families have the same frameshift), 1 is a canonical splice. All families had adult onset of symptoms ranging from 20-63yo. All has white matter hyper intensity on imaging.; to: New MOI Mono-allelic LAMB1 variants reported in 5 families with cerebral small vessel disease. 4 are truncating frameshifts (and 2 of the families have the same frameshift), 1 is a canonical splice.
