Twins With Feingold Syndrome: Overview and Interview/Twin Research Summaries: Pseudoamonoamniotic Twins; Selective Fetal Growth Restriction in Monoamniotic Twins; Twin Authorship Attribution; Twins Discordant for Clubfoot/Human Interest: Twins with Different Fathers; Biological Relatedness in a Married Couple; Birth of Identical Quadruplets; Twins Switching Places.

A pair of young monozygotic male twins affected with Feingold syndrome were briefly described in previous issues of Twin Research and Human Genetics. An opportunity to meet the twins and their mother occurred in March 2026. An overview of the condition and interview with the twins' mother is presented, as are implications for future research and practice. Next, research summaries of pseudoamonoamniotic twins, selective fetal growth restriction in monoamniotic twins, twin authorship attribution, and twins discordant for clubfoot are provided. This article concludes with human interest stories involving twins with different fathers, biological relatedness in a married couple, the birth of identical quadruplets, and twins switching places.
