Interstitial deletions of chromosome 3p are rare, and specific genotype-phenotype correlations cannot always be assessed. We report the case of a 3p14.2 proximal microdeletion in a 60-year-old female patient with mild intellectual disability, severe speech delay, and mild dysmorphism. An array-CGH analysis detected a 500-kb deletion in the 3p14.2 region, including , , and . and are known to network within the neurodevelopmental pathways. It is possible that their rearrangements lead to the phenotypic features observed in the patient, and therefore, they can be considered candidate genes responsible for such abnormalities.
3号染色体短臂的间质缺失很少见,且特定的基因型-表型相关性并非总能评估。我们报告了一例60岁女性患者,其3p14.2近端微缺失,伴有轻度智力障碍、严重语言发育迟缓及轻度畸形。阵列比较基因组杂交(array-CGH)分析检测到3p14.2区域有一个500kb的缺失,包括……和……。已知……和……在神经发育途径中形成网络。它们的重排可能导致患者出现所观察到的表型特征,因此,可将它们视为导致此类异常的候选基因。
