Data from the GUDMAP renal expression database (http://www.gudmap.org), supports our findings: NFATc3 expression is shown by in situ hybridisation in the E15.5 UB, MM, tubules, and renal interstitium (Andrew McMahon lab), and microarray data reveals NFATc3 expression in the UB, MM, renal vesicles, s-shaped bodies, and podocytes at E11.5–15.5; microarray analysis of NFATc4 expression also detected transcripts in the UB, renal vesicles, podocytes, and proximal tubules at E11.5–15.5, with very high expression in the E11.5 MM, confirming our RT-PCR data. Here, NFATC4 is linked to Miyoshi myopathy.
