Deconvolution rules a tool to solve a complex paternity case where child was chimeric

STR-autosomal markers are among the most powerful systems to solve kinship attribution cases. The Y-STR chromosome analysis is another widely accepted system to confirm the parental relation alleged father-son. Here, we show an unusual Civil trial where a woman (VE) wanted to know whether a man (MR) was the father of her child (VM). Four years earlier, the child had been hospitalised in a Paediatric Onco-Haematology department. He had haematopoietic stem cell transplantation (HSCT) for a leukaemia disease. His mother was the donor.
