Nonsense variants of STAG2 result in distinct congenital anomalies

Herein, we report two female cases with novel nonsense mutations of STAG2 at Xq25, encoding stromal antigen 2, a component of the cohesion complex. Exome analysis identified c.3097 C>T, p.(Arg1033*) in Case 1 (a fetus with multiple congenital anomalies) and c.2229 G>A, p.(Trp743*) in Case 2 (a...

Description
Summary:Herein, we report two female cases with novel nonsense mutations of STAG2 at Xq25, encoding stromal antigen 2, a component of the cohesion complex. Exome analysis identified c.3097 C>T, p.(Arg1033*) in Case 1 (a fetus with multiple congenital anomalies) and c.2229 G>A, p.(Trp743*) in Case 2 (a 7-year-old girl with white matter hypoplasia and cleft palate). X inactivation was highly skewed in both cases.
