ABSTRACT
We present here the first case of constitutional tetrasomy 18p from India. A 3 year old female with developmental delay and dysmorphic features revealed 47,XX,+mar karyotype. The small meta-centric marker chromosome was identified as i(18p) with m-FISH followed by m-BAND. Parents and a normal sibling of the proband revealed normal karyotype. There was history of mental retardation and dysmorphic features in four cases on paternal side; however, their karyotype was also normal.
