We report on a newborn with IUGR, rhizomelic dwarfism, and suspected chondrodysplasia punctata. At birth, OI was suspected; however, a skeletal survey suggested ML II alpha/beta. Sequencing revealed compound heterozygosity for a reported pathogenic and novel but expected pathogenic variant. Molecular testing for autosomal recessive OI identified a variant.
我们报告了一名患有宫内生长受限、短肢侏儒症且疑似点状软骨发育不良的新生儿。出生时怀疑患有成骨不全症(OI);然而,骨骼检查提示为II型粘多糖贮积症(ML II alpha/beta)。测序显示存在一个已报道的致病突变和一个新的但预期致病的变异的复合杂合性。常染色体隐性成骨不全症的分子检测确定了一个变异。
