| Remarks |
SUG17802: 45 year old Ashkenazi Jew originally from Germany. Bilateral ocular cataracts, tight atrophic skin with ulceration, short stature, premature graying and thinning of hair, type II diabetes mellitus, hypogonadism, marked soft tissue calcification, high pitched voice, flat feet. The donor subject is a compound heterozygote; one allele of the RECQL2 gene has a large deletion >15kb within IVS18 and IVS23 which results in a loss of exons 19-23, a frameshift and truncation, and the other allele has a nonsense mutation at amino acid 889 due to a C to T transition at nucleotide 2896 in exon 20 (2896C>T) resulting in Arg(CGA)>Ter(TGA) [ARG889TER(R889X)]. The culture is a mosaic with karyotype: 46,XY[96]/46,XY,t(13;16)(13pter>13q14::16q24>16qter;16pter>16q24::13q24>13qter)[4] with 6% of the cells examined showing random chromosome loss/gain. The legacy karyotype description shown in this Remark may not be representative of the current available product. |
