Rhizomelic chondrodysplasia punctata (RCDP) is one of the rare peroxisomal disorder (autosomal recessive inheritance) due to altered phytanic acid alpha oxidation and plasmalogen synthesis. RCDP 1 is the most frequent form of RCDP. It is a peroxisomal biosynthesis disorder. RCDP 2 and RCDP 3 are disorders of individual peroxisome enzyme. Authors described a case of RCDP type 2 in a 13 months old girl with characteristic features of typical chondrodysplastic facies, bilateral cataract, rhizomelic shortening of limbs, growth and global developmental delay; radiological features showed epiphyseal stippling. Genetic analysis showed apparent homozygous deletion of c.1848delC after full sequencing of her GNPAT genes.
