Diagnosis of X-recessive Kallmann syndrome in early infancy. Evidence of hypoplastic rhinencephalon

Eur J Pediatr. 1994 Apr;153(4):245-7. doi: 10.1007/BF01954511.

Abstract

A 3-month-old infant presented with hypogonadism, a small penis and bilateral cryptorchidism. He showed an insufficient response of luteotropic hormone (LH) and follicle stimulating hormone (FSH) to luteotropic hormone releasing hormone (LHRH) and of testosterone to human chorionic gonadotropin. The maternal uncle had hypogonadism and anosmia and also showed an impaired LH and FSH response to LHRH. MRI examination showed hypoplasia of the rhinencephalon in both cases. These findings in the son and brother of the clinically unaffected mother suggest X-linked recessive inheritance.
