Abstract
Chromosome 15q26 deletion is a rare condition that causes short stature and is associated with intrauterine growth restriction (IUGR), failure to thrive, congenital heart disease and many congenital malformations. The insulin growth factor receptor (IGF-1R) on chromosome 15 has many important roles, especially in growth regulation. Our case is an 18-month-old small for gestational age girl who presented with severe short stature, microcephaly and minor dysmorphic features. Chromosome microarray revealed 15q26 deletion including the IGF1R gene. Recombinant growth hormone (rGH) has been used in patients with IGF-1R defects with variable treatment responses. The reason for rGH unresponsiveness in some patients with terminal chromosome 15q deletion is still unclear. Herein we discuss the use of rGH in a patient with heterozygous IGF1R deletion and emphasize the need for further follow-up regarding other endocrine disorders.
