Copy number variation in loss of 3p13 is an infrequently reported entity characterized by hypertelorism, aniridia, microphthalmia, high palate, neurosensorial deafness, camptodactyly, heart malformation, development delay, autism spectrum disorder, seizures, and choanal atresia. The entity is caused probably by haploinsufficiency for and We report a newborn male with hypotonia, facial dysmorphism, heart malformation, and without clinical diagnosis; nevertheless, the use of appropriate genetic test, such us the chromosomal microarray analysis allowed identification of a copy number variant in loss of 5.5 Mb at chromosome 3 (p13-p14.1), that included 54 genes, encompassing gene. We compare the findings in our Peruvian patient to those of earlier reported patients; furthermore, add new signs for this entity.
3p13缺失的拷贝数变异是一种报道较少的病症,其特征为眼距过宽、无虹膜、小眼畸形、高腭弓、神经性耳聋、屈曲指、心脏畸形、发育迟缓、自闭症谱系障碍、癫痫发作和后鼻孔闭锁。该病症可能是由于[相关基因]单倍剂量不足所致。我们报告了一名患有肌张力减退、面部畸形和心脏畸形且未明确临床诊断的新生儿男性;然而,通过使用适当的基因检测,如染色体微阵列分析,发现该患儿在3号染色体(p13 - p14.1)上存在5.5 Mb的缺失拷贝数变异,其中包含54个基因,涵盖了[相关基因]。我们将这位秘鲁患者的研究结果与早期报道的患者进行了比较;此外,还为该病症增添了新的体征。
