Infertility and Recurrent Pregnancy Loss v0.210 C4BPA Zornitza Stark Marked gene: C4BPA as ready
Infertility and Recurrent Pregnancy Loss v0.210 C4BPA Zornitza Stark Gene: c4bpa has been classified as Amber List (Moderate Evidence).
Infertility and Recurrent Pregnancy Loss v0.210 C4BPA Zornitza Stark Phenotypes for gene: C4BPA were changed from recurrent pregnancy loss susceptibility to recurrent pregnancy loss susceptibility MONDO:0000144, C4BPA-related
Infertility and Recurrent Pregnancy Loss v0.209 C4BPA Zornitza Stark Classified gene: C4BPA as Amber List (moderate evidence)
Infertility and Recurrent Pregnancy Loss v0.209 C4BPA Zornitza Stark Gene: c4bpa has been classified as Amber List (Moderate Evidence).
Infertility and Recurrent Pregnancy Loss v0.103 C4BPA Jasmine Chew changed review comment from: PMID: 23508668- Five unrelated female with history of recurrent RPL (<10 weeks) carrying het missnese variants (See table 3- G423E, R120H, I126T, P4Q). l. The I126T mutation in CCP2 of C4BP α-chain is of particular interest as it was found only in one patient but not in healthy controls. This rare mutation affected both expression level of C4BP α-chain as well as its function, i.e., degradation of C4b and C3b in solution. R120H, found in two patients and no controls, increased the ability of C4BP to act as cofactor in degradation of C4b but decreased its activity in degradation of C3b both in solution and deposited on the cell surface. The other 2 variants have been observed in controls. However, they observed that homozygous C4BP knockout mice often die during second or third pregnancy (unpublished observation). This would imply a pivotal role of this protein in maintenance of successful pregnancy, although the mechanism is not known.
