TRPM3 and Neurodevelopmental delay: These TRPM3-NDD studies focused on transcript variant-14 (NM_001366145.2) coding for channel isoform-m (NP_ 1353074.2, 1719 amino-acids) that starts in exon-2 but contains one more coding exon (exon-16, 12 amino acids) than the variant-9/isoform-k (1707 amino-acids) used here (Figure S1).
