Dr. Nara Lygia De Macena Sobreira is an assistant professor at the McKusick-Nathans Department of Genetic Medicine at Johns Hopkins University School of Medicine. Her area of expertise is rare Mendelian phenotypes, analysis of next-generation sequencing, and functional testing of candidate causative variants. She earned her M.D. at the University of Pernambuco in Brazil. She finished her Ph.D. in Human Genetics at Johns Hopkins followed by a one-year postdoc also at Johns Hopkins School of Medicine. During her Ph.D., she worked with Dr. David Valle using next-generation sequencing to elucidate the molecular basis of rare Mendelian phenotypes and in 2010 she discovered PTPN11 as the gene responsible for metachondromatosis by using whole-genome sequencing. She completed residencies in clinical genetics at both Universidade Federal de Sao Paulo and Johns Hopkins. Her main clinical and research focus is on identifying the genetic bases of rare phenotypes, mainly, phenotypes associated with cartilage tumors and vascular anomalies (including Ollier disease and Maffucci syndrome), and on understanding the physiopathology of these phenotypes to identify pharmacological strategies to treat them. She has worked extensively on developing strategies to better analyze the variants identified by next-generation sequencing and on novel strategies for data sharing. She participated on the development of PhenoDB, a phenotypic and genomic database, and created PhenoDB Variant Analysis Tool used worldwide. She is also one of the creators of GeneMatcher, VariantMatcher, and one of the co-founders of the Matchmaker Exchange, all intended to share next-generation sequencing data. She has also worked extensively on functional studies that evaluate the possible pathogenic effects of the candidate causative variants.

Nemours Children's Hospital, Delaware
I was born in India to a family of doctors, so I did not have to look far for inspiration. I’m married to a pediatric cardiologist, also with duPont Hospital for Children, and I’m grateful for the opportunities I have every day to improve lives for kids and their families. As a father and surgeon, I have a soft spot for helping children in any way I can. It’s a privilege to be able to improve their lives even if there are challenges. I love to see kids getting back to enjoying life to its fullest and being able to help people deal with difficult issues. One of my proudest professional moments was the day I walked into the operating room and had the privilege to start surgically caring for children. I’m still passionate about my work and the opportunities I have every day to improve the lives of kids, one child at a time. The children I treat have serious medical problems, and it takes a whole team of professionals, working in lots of related medical and sociological fields, to make a difference in their lives, and the lives of their families. It’s an honor to be part of that team. At the end of the day, it’s all about the kids. Dr. Thacker is rated as an Experienced provider by MediFind in the treatment of Schwartz-Jampel Syndrome.
