ADGRB3 69,345,259–70,099,403 adhesion G protein-coupled receptor B3 602684 3.02 no reported phenotype association; homologous to ADGRB1, an angiogenesis inhibitor that is a candidate for involvement in development of glioblastoma41
LMBRD1
(disrupted)
70,385,694–70,507,003 LMBR1 domain containing 1 612625 + + 12.92 biallelic loss of function (autosomal recessive) associated with methylmalonic aciduria and homocystinuria, cblF type42
(no phenotypic overlap with DGAP239)
