Objective

Recurrent pregnancy loss (RPL) is a common infertility-related complication that affects approximately 1-3 % of women worldwide. Known causes of etiology are found in approximately half the cases but the other half remain unexplained. It is estimated that several thousands of genes contribute to reproductive success in mammals and the genetic causes of RPL cannot be fully addressed through targeted genetic tests. In recent years, massive parallel sequencing technologies has helped discovering many causal mutations in hereditary diseases such as RPL.

Study design

Using whole-exome sequencing (WES), we studied a large multiplex consanguineous family with multiple cases of RPL and hydatidiform moles (HM). In addition, targeted Sanger sequencing was applied to 40 additional non-related individuals with RPL.

Results

The use of WES permitted to identify the pathogenic variant in KHDC3L (c.322_325delGACT) in related who experienced RPL with or without HM. Sanger sequencing confirmed the segregation of the mutation throughout the pedigree and permitted to establish this variant as the genetic cause responsible for RPL and HM in this family.

Conclusion

KHDC3L is well established as a susceptibility gene for HM but we confirmed here that KHDC3L deleterious variants can also induce RPL. In addition, we observed a genotype-phenotype correlation, demonstrating that women with a truncating KHDC3L homozygous variant could not sustain a pregnancy and often had pregnancy losses mainly due to HM while those with the same heterozygous variant could have children but often endured RPL with no HM."xsd:string
