Gaucher disease is the most common sphingolipid storage disorder. Due to its high prevalence it may appear with a nonrelated neurological disease and be misinterpreted as Gaucher type 3. A family is described in which 2 Gaucher brothers presented different clinical signs. Molecular analysis has shown that both carried two mutated alleles. One allele had a G to C transversion at nucleotide 3119 of the active gene (Asp140-His) while the other presented two base pair changes, an A to C transversion at nucleotide number 3170 (Lys157-Gly), and a G-A transition at nucleotide number 5309 (Glu324-Lys). Therefore, both presented the same type of Gaucher disease which was accompanied with a nonrelated neurological disease in one of them. Molecular diagnosis of 161 patients has provided a relative abundance of different mutations among Jewish and non-Jewish patients and allowed some genotype-phenotype correlation. Differential expression of the murine glucocerebrosidase activator gene (the prosaposine) has been demonstrated using Northern technique and in situ hybridization. High expression levels were observed in the brain and testes. In the testes the prosaposine expression was confined to the supporting cells. In the female gonad prosaposine expression has also been shown, in the corpus luteum. In a 12 1/2-day-old embryo, prosaposine gene expression was detected mainly in brain stem, in dorsal ganglia and in the genital ridge.

D010053 Ovary The reproductive organ (GONADS) in female animals. In vertebrates, the ovary contains two functional parts: the OVARIAN FOLLICLE for the production of female germ cells (OOGENESIS); and the endocrine cells (GRANULOSA CELLS; THECA CELLS; and LUTEAL CELLS) for the production of ESTROGENS and PROGESTERONE. Ovaries
D011498 Protein Precursors Precursors, Protein
D011544 Pseudogenes Genes bearing close resemblance to known genes at different loci, but rendered non-functional by additions or deletions in structure that prevent normal transcription or translation. When lacking introns and containing a poly-A segment near the downstream end (as a result of reverse copying from processed nuclear RNA into double-stranded DNA), they are called processed genes.
