      Acromesomelic dysplasia, type Maroteaux is a disorder characterized by disproportionate short stature predominantly affecting the middle and distal segments of the upper and lower limbs. It is an autosomal recessive disorder due to mutation in NPR2 gene which impairs skeletal growth. To screen the mutations in the gene NPR2, all of its coding exons and splice junction sites were PCR amplified from genomic DNA of affected individuals of four families and sequenced. Four homozygous mutations in four different families were identified. These include three novel mutations including a deletion frameshift mutation (p.Cys586Ter), one nonsense mutation (p.Arg479Ter), one missense mutation (p.Val187Asp) and one reported missense mutation (p.Tyr338Cys). The study describes phenotypes of Indian patients and expands the mutation spectrum of the disorder.

      Emanuel syndrome is caused due to an additional derivative chromosome 22 and is characterized by severe intellectual disability, microcephaly, failure to thrive, preauricular tags or pits, ear anomalies, cleft or high-arched palate, micrognathia, kidney abnormalities, congenital heart defects and genital abnormalities in males. In 99% of the cases, one of the parents is a carrier of balanced translocation between chromosomes 11 and 22. It occurs due to malsegregation of the gametes with 3:1 segregation. In this case series, we describe four patients with diverse manifestations of this condition. The craniosynostosis observed in one case isa novel finding which has never been reported previously. This study aims to widen the phenotypic spectrum of Emanuel syndrome and provide cytogenetic microarray based breakpoints in two of the cases, thus supporting close clustering of the breakpoints of this common recurrent chromosomal rearrangement.
