Hypogonadotropic hypogonadism presenting with arhinia: a case report

Year: 2013

Type: article

Abstract: INTRODUCTION: Arhinia, congenital absence of the nose, is a rare malformation. We present the third reported case of arhinia accompanied by hypogonadism and demonstrate that this is due to gonadotropin deficiency. CASE PRESENTATION: A 13-year-old Caucasian boy with congenital arhinia presented for evaluation of delayed puberty and micropenis. We examined genes known to be associated with hypogonadotropic hypogonadism for mutations and performed a chromosomal microarray to assess copy number variation. CONCLUSION: No mutations in KAL1, FGFR1, PROK2, PROKR2, FGF8, CHD7 and GnRHR were identified in our patient and there were no copy number variations observed that would explain the phenotype. Though studies are limited in such patients, we suggest that hypogonadotropic hypogonadism is associated with arhinia and that the two entities likely result from a common genetic cause that affects early nasal development and gonadotropin-releasing hormone neuron formation or migration.
