Exclusively paternal X chromosomes in a girl with short stature

A A Schinzel et al. Hum Genet. 1993 Sep.

Abstract

A 13 1/2 year-old girl with short stature and very few Turner stigmata revealed 45,X/46,XX mosaicism with 90%-100% 46,XX cells in three sequential blood lymphocyte cultures. Molecular investigation of the parental origin of her X chromosomes revealed homozygosity for paternal X markers and an absence of maternal markers. Luteinizing hormone response to growth hormone releasing hormone was increased. Impaired gonadal function and shortness of stature in this case could be a result of the mild mosaicism with a 45,X cell line and/or is a consequence of the paternal-only origin of her X chromosomes.
