Ayurveda Renaissance – Quo Vadis?
Published in D. Suresh Kumar, Ayurveda in the New Millennium, 2020
Several methylated sequences of vāta prakṛti were found to be represented in biological processes like cell communication, transcription, signal transduction pathways and embryo morphogenesis. The associated genes are involved especially in neuronal development. Additionally, the NFIX gene was found to be associated with low body mass index (B.M.I.) which is one of the characteristic signs of vāta prakṛti (Rotti et al. 2015).
Sotos Syndrome
Published in Dongyou Liu, Handbook of Tumor Syndromes, 2020
It should be noted that mutation in the nuclear factor I/X type gene (NFIX) on chromosome 19p13.3 may produce an autosomal dominant disorder known as Malan syndrome (or Sotos syndrome 2) [11–13]. Nuclear factor I is a ubiquitous 47-kD dimeric DNA-binding protein with the capability of stimulating the transcription of genes in cooperation with other factors such as estrogen receptor (ESR). In addition, alteration in the APC2 gene on chromosome 19p13.3 may cause an autosomal recessive disease known as Sotos syndrome 3. APC2 is a 2303-aa protein gene preferentially expressed in postmitotic neurons. As NSD1 is shown to downregulate APC2 in neurons, it is no surprise that Apc2-deficient (Apc2−/−) mice exhibit impaired learning and memory abilities along with an abnormal head shape [14,15]. Given that the mitogen-activated protein kinase (MAPK) pathway is a diminished activity state in Sotos syndrome, it may be also involved in statural overgrowth and accelerated skeletal maturation [16]. In addition, NSD1 forms as a fusion transcript with NUP98, playing a part in leukemogenesis through H3K36 methylation and subsequent HOX-A gene activation, particularly childhood acute myeloid leukemia [17].

According to the National Human Genome Research Institute Catalogue of Published GWAS studies [86], there are 97 studies published to date with a focus on BD. These have identified associations with 961 loci with varying levels of genome-wide significance in different populations and specific phenotypes. The strongest hits are described in Table 3 and include genes with reported roles in calcium signaling (CACNA1C), hydrolase activity (TRANK1), cell cycle control (MAD1L1), cytoskeleton (ANK3), fatty acids metabolism (FADS2), secretory pathways (LMAN2L), phosphoprotein phosphatase activity (PPM1M), transcription factor activity (NFIX), neuronal connectivity (ODZ4), among others. It is worth mentioning that enrichment analyses found limited overlap between blood-based proteomics, as discussed in the previous section, and genetic loci identified in GWAS in BD [74].
