A deletion mutation in GDF9 in sisters with spontaneous DZ twins.
A loss of function mutation in growth differentiation factor 9 (GDF9) in sheep causes increased ovulation rate and infertility in a dosage-sensitive manner. Spontaneous dizygotic (DZ) twinning in the human is under genetic control and women with a history of DZ twinning have an increased incidence of multiple follicle growth and multiple ovulation. We sequenced the GDF9 coding region in DNA sam...
متن کاملNovel variants in growth differentiation factor 9 in mothers of dizygotic twins.
CONTEXT Genes from the ovarian bone morphogenetic signaling pathway (GDF9 and BMP15) are critical for normal human fertility. We previously identified a deletion mutation in GDF9 in sisters with spontaneous dizygotic (DZ) twins, but the prevalence of rare GDF9 variants in twinning families is unknown. OBJECTIVE The objective was to evaluate the frequency of rare variants in GDF9 in families w...
متن کاملGNE Myopathy in Turkish Sisters with a Novel Homozygous Mutation
Background. Hereditary inclusion body myopathy is caused by biallelic defects in the GNE gene located on chromosome 9p13. It generally affects adults older than 20 years of age. Methods and Results. In this study, we present two Turkish sisters with progressive myopathy and describe a novel mutation in the GNE gene. Both sisters had slightly higher levels of creatine kinase (CK) and muscle weak...

متن کاملa novel deletion mutation of the tyr gene in a patient with oculocutaneous albinism type 1a
introduction oculocutaneous albinism (oca) is a genetically heterogeneous autosomal recessive genetic disorder that is characterized by reduced or completely absent pigmentation in the hair, skin, and eyes. conclusions a novel homozygous mutation, the deletion of exons 1 - 5 on the tyr gene, was found on the molecular genetic testing of this patient. exon 1 - 5 deletion on tyr causes a lack of ...
