About BLM

Cytogenetic location: 15q26.1 Genomic coordinates (GRCh38): 15:90,717,346-90,816,166 (from NCBI)

This gene has 13 transcripts (splice variants), 200 orthologues, 4 paralogues and is associated with 98 phenotypes. Biased expression in salivary gland (RPKM 10.0), lymph node (RPKM 3.9) and 12 other tissues.

Summary

The Bloom syndrome is an autosomal recessive disorder characterized by growth deficiency, microcephaly and immunodeficiency among Others. It is caused by homozygous or compound heterozygous mutation in the gene encoding DNA helicase RecQ protein on chromosome 15q26. This Bloom-associated helicase unwinds a variety of DNA substrates including Holliday junction, and is involved in several pathways contributing to the maintenance of genome stability. Identification of pathogenic Bloom variants is required for heterozygote testing in at-risk families. [provided by RefSeq, May 2020]
