Syed Qasim Mehdi, Pakistani geneticist and molecular biologist (Lucknow 13 February 1941 – Lahore 28 September 2016) 

His discoveries have shown eight new mutations in the tumour suppressor gene p53 in breast cancer patients, four new genetic loci responsible for night blindness and new genes responsible for non-syndromic deafness and microphthalmia in Pakistani families (until 1998)
