The mining of damaging nsSNPs was carried out based on the evolutionary conservation of sequence information, prediction of protein stability, interaction analysis, and their potential impact was assessed using structure prediction and 3D modeling, and interaction with other genes\/pathways.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In the initial screening, SIFT, PolyPhen\u20102, SNAP2, Align GVGD, PhD\u2010SNP, PANTHER, and SNPs&amp;GO revealed 23 potential deleterious SNPs in\n                      <jats:italic>MCPH1<\/jats:italic>\n                      . Population frequency analysis using gnomAD revealed that the prioritized variants were extremely rare in the global population. I\u2010mutant and ConSurf further revealed that 16 nsSNPs exhibited a decrease in protein stability due to changes in size and charge. I\u2010TASSER was used to predict wild\u2010type and mutant protein 3D structures. The potential effect of variation on 3D protein structure was assessed using the Chimera tool, which presented the probable structural loss in eight variants, including p.A11D, p.H49D, p.T59I, p.W60S, p.W60C, p.L74P, p.C79G, and p.L781P. Most of these potential variants resided in the\n                      <jats:italic>N<\/jats:italic>\n                      \u2010terminal BRCT domain, which is implicated in neurodevelopment, and thus may lead to the pathogenesis of primary microcephaly. Furthermore, single\u2010cell transcriptomic mapping of MCPH1 against dataset of 33,206 cells from malformations of cortical development detected MCPH1 expression across multiple cellular populations. This broad distribution suggested potential MCPH1 function across several neural and glial cell populations.\n                    <\/jats:p>\n                  <\/jats:sec>\n
