Remarks |
Clinically affected; diagnosed with osteosarcoma at age 21 years; small stature; severe poikiloderma; sparse eyebrows, eyelashes and hair; brother had RTS and died of metastatic osteosarcoma; donor is the son of AG18376/AG18459 (mother) and AG18377 (father); AG18375 is a fibroblast culture from the same donor; the donor subject is a compound heterozygote; in allele one at nucleotide g.2626 there is a G>A substitution (g.2626G>A) in exon 8 of the RECQL4 gene which leads to disrupted splicing; in allele two there is a 1 bp deletion at g.2886 (g.2886delT) in exon 9 of the RECQL4 gene which leads to a truncation. The karyotype is 46,XY with 2% of the cells examined showing random chromosome loss and 6% showing random chromosomal aberrations. The legacy karyotype description shown in this Remark may not be representative of the current available product. |
