Genetic Counselling an Personalized Medicine conference in Hyderabad

Delighted to be a part of 8th Annual BGCI #conference held at the #University of Hyderabad from July 7th to 9th, 2023 where Rakesh Sharma, PhD and Madhuri R presented posters titled “Molecular landscape of #lung adenocarcinoma in India for personalizing therapy” and “Driver gene alterations in EGFR and IDH1 are mutually exclusive in Indian Gliomas”.

Jugnu Jain and Kalpana Kannabiran were invited by Dr Q. Annie Hasan to chair the session on “Psychosocial #ethical and legal issues in #genetics and #genomics ” including panelists Dhavendra kumar Mahati Chittem Saveetha Meganathan, Kelly Ormond and Peter Abad.
Reena Trivedi Vaishnavi Suresh helped put the panel together.

It was an enriching experience, filled with insightful presentations and discussions.

HER2 Oncogenic mutations and amplifications are common across many Indian solid tumors

Until recently, HER2 (or ErbB2) targeting drugs were only approved for HER2-amplified breast & gastric cancers. FDA has now granted accelerated approval for trastuzumab or Enhertu to treat lung cancer patients bearing activating HER2 mutations. We analyzed our data of ~1000 solid cancer cases generated using the OncomineTM Dx NGS panel to determine the pattern of ERBB2 amplification vs. mutations. We see that in some cancers, amplifications are more common (breast, gastric, endometrial cancers) but in others, activating mutations are more common (colorectal, lung, thyroid and gliomas) with the most common mutation being V842I in Indian samples. Molecular insights gained from such NGS analysis can hopefully improve precision medicine by expanding the use of approved HER2-targeting drugs for colorectal, endometrial, gliomas, thyroid and other cancer patients that are likely to benefit from them.

Our paper is out in Frontiers in Pharmacology

Our paper on first ever reported establishment of a cell culture from a rare brain tumor (DIG glioma), is published in Frontiers in Pharmacology journal, with Impact factor of 4.5. Such primary cultures are very useful for drugdevelopment and phenotypic screening.
