Figure 1. Rare CNVs related to folate and Vitamin B12 metabolism.

Figure 1

(A) SNP-array shows a 4.8 Mb duplication at 5q14.1 (chr5:75132315-79958945); (B) A 175-kb duplication at 10p13 (chr10:16883466-17058324) (UCSC Genome Browser on Human GRCh37/hg19 Assembly). Log R ratio and B alle frequency are showed in the upper panel and annotated genes are listed in the lower panel. (C) Summary of Folate metabolic pathway (Methionine-Homocysteine-Folate-B12 Cycle). DHF, dihydrofolate; THF, tetrahydrofolate; DHFR, dihydrofolate reductase; MTHFR, methylenetetrahydrofolate reductase; SHMT, serine hydroxyl-methyltransferase; MAT, methionine adenosyltransferase; SAH, S-adenosylhomocysteine; SAM, S-adenosylmethionine; MTR, methionine synthase; PRMT, protein arginine methyltransferase; CUBN, Cubilin.
