The dysmorphic facies, renal agenesis, ambiguous genitalia, microcephaly, polydactyly, and lissencephaly (DREAM-PL) syndrome is a rare autosomal recessive disorder characterized by dysmorphic facies, renal agenesis, ambiguous genitalia in males, microcephaly, polydactyly, and lissencephaly. The CTU2 gene, which encodes a protein involved in the post-transcriptional modification of tRNAs is the source of the syndrome's mutation. Several developmental abnormalities can result from a disruption of this modification, which is necessary for the proper translation of genes. The severity of the symptoms of DREAM-PL syndrome can range from moderate to severe, and its clinical characteristics are quite diverse. Some patients might have some of the distinguishing characteristics, whereas others might have all of them. The most typical characteristics include ambiguous genitalia, dysmorphic facies, and microcephaly. DREAM-PL syndrome is diagnosed based on clinical signs and genetic testing which can show mutations in the CTU2 gene. Although there is no known cure for this syndrome, the treatment aims to manage the symptoms. Other lines of treatment like surgical correction of birth defects can sometimes be beneficial to these patients in addition to supportive care. This study is a report of a 37-week-old male neonate, delivered by lower segment cesarean section. The baby's birth weight is 2.760 kg with a heterozygous confirmed pathogenic mutation of the CTU2 gene confirmed by whole-exome sequencing.
畸形面容、肾缺如、生殖器模糊、小头畸形、多指畸形和无脑回(DREAM - PL)综合征是一种罕见的常染色体隐性疾病,其特征为畸形面容、肾缺如、男性生殖器模糊、小头畸形、多指畸形和无脑回。编码参与tRNA转录后修饰的蛋白质的CTU2基因是该综合征突变的来源。这种修饰的破坏可导致多种发育异常,而这种修饰对于基因的正确翻译是必需的。DREAM - PL综合征症状的严重程度可从中度到重度,其临床特征非常多样。一些患者可能有部分特征,而另一些患者可能具备所有特征。最典型的特征包括生殖器模糊、畸形面容和小头畸形。DREAM - PL综合征根据临床体征和基因检测进行诊断,基因检测可显示CTU2基因的突变。虽然该综合征尚无已知的治愈方法,但治疗旨在控制症状。除了支持性护理外,其他治疗方法如对出生缺陷进行手术矫正有时对这些患者有益。本研究报告了一名37周龄的男性新生儿,通过下段剖宫产分娩。婴儿出生体重为2.760千克,全外显子测序证实其CTU2基因存在杂合性确认致病突变。
