HPS4272 :  update : 2023/09/12
CommentDisease specific iPS cell line derived from a patient : Down syndrome, trisomy 21. HPS4270, HPS4271, HPS4272, HPS4273 were derived from the same patient.
Comment from the depositorInduced disomy 21 iPS cell line [46,XY] by elimination of the paternal origin of the chromosome 21 (M1) from HPS4270 (Disease specific iPS cell line derived from a person with Down syndrome, [47,XY,+21])
