| Gene |
RECQL3 |
| Chromosomal Location |
15q26.1 |
| Allelic Variant 1 |
604610.0001; BLOOM SYNDROME |
| Identified Mutation |
6-BP DEL/7-BP INS; In 4 ostensibly unrelated persons of Jewish ancestry, Ellis et al. [Cell 83: 655 (1995)] found homozygosity for a 6-bp deletion/7-bp insertion at nucleotide 2281 of the BLM cDNA. Deletion of ATCTGA and insertion of TAGATTC caused the insertion of the novel codons for LDSR after amino acid 736, and after these codons there was a stop codon. Ellis et al. [Cell 83: 655 (1995)] concluded that a person carrying this deletion/insertion mutation was a founder of the Ashkenazi-Jewish population, and that nearly all Ashkenazi Jews with Bloom syndrome inherited the mutation identical by descent from this common ancestor. |

| Remarks |
Clinically affected; B. S. Registry # 107; increased sister chromatid exchange; diffuse histiocytic tonsil lymphoma diagnosed at age 26 years; breast carcinoma diagnosed at age 34 years; biopsy taken from the cervix uteri at time of surgery for cancer; one affected sister; donor subject is homozygous for a 6-bp deletion/7-bp insertion [6-bp del/7-bp ins] at nucleotide 2,281 of the open reading frame of the RECQL3 gene, which results in a frameshift and a stop codon. |
