The p.Thr395Met missense variant of NFIA found in a patient with intellectual disability is a defective variant.

Nuclear factor one A (NFIA) is a transcription factor that regulates the development of the central nervous system. Haploinsufficiency of the NFIA gene causes NFIA-related disorder, which includes brain abnormalities and intellectual disability, with or without urinary tract defects. Intragenic deletions, nonsense variants, frameshift variants, and missense variants in one allele of the NFIA gene have been reported to cause various neurological and urogenital symptoms.

Direct-TRI: High-throughput RNA-extracting Method for All Stages of Zebrafish Development.

Recent popularization of next-generation sequencing enables conducting easy transcriptome analysis. Nevertheless, substantial RNA isolation work prior to RNA sequencing, as well as the high cost involved, still makes the routine use of large-scale transcriptome analysis difficult. For example, conventional phenol-chloroform RNA extraction cannot be easily applied to hundreds of samples.

Loss of αklotho causes reduced motor ability and short lifespan in zebrafish.

The klotho gene encodes a transmembrane protein αKlotho that interacts with a fibroblast growth factor (FGF) receptor in renal tubular epithelial cells and functions as a co-receptor for FGF23, which is an osteocytes-derived hormone. This bone-to-kidney signal promotes urinary phosphate excretion. Interestingly, αKlotho knockout mice show an accelerated aging and a shortened life span.
