SMN1 and proximal spinal muscular atrophy: We previously showed hepatocyte-intrinsic steatosis in SMA, raising the question of whether SMA carriers, who are typically asymptomatic, may also exhibit subclinical hepatic abnormalities.<h4>Methods</h4>We generated induced hepatocyte-like cells (iHeps) from induced pluripotent stem cells (iPSCs) derived from an SMA Type 2 proband, his isogenic wild-type (Iso-WT) line, and both carrier parents, comprised of three carrier lines from the father and one from the mother.
