Cardiac expression of 52β, an alternative transcript of the congenital heart block‐associated 52‐kd SS‐A/Ro autoantigen, is maximal during fetal development
1 Apr 1997
Abstract excerpt
OBJECTIVE: Congenital heart block (CHB), associated with antibodies to SS-A/Ro and SS-B/La, is most often detected between 18 and 24 weeks of gestation, yet the maternal heart is unaffected. We recently described an alternatively spliced 52-kd SS-A/Ro messenger RNA (mRNA) derived from the skipping of exon 4 which encodes a smaller protein, 52beta (MW 45 kd), recognized by CHB maternal antisera. This study was...
