A full-term male infant born from consanguineous Saudi parents, with one other live child, is suspected to have skeletal dysplasia on a fetal anomaly scan. Clinical findings at birth included short stature, bowed long bone affecting the lower limbs more than the upper limbs, severe joint contractures with restricted movement, failure to thrive, hypertonia, and camptodactyly of the index fingers. During infancy, the baby is noted to have sucking and swallowing difficulties necessitated nasogastric tube feeding, and recurrent respiratory distress episodes with frequent admissions due to respiratory failure required intensive care admission and mechanical ventilation. The skeletal survey demonstrated dysplasia of long bones and spine. To investigate a suspect genetic syndrome, a whole-exome sequencing test was performed, which identified a novel homozygous mutation in the gene.
一名足月男婴,其父母为沙特近亲结婚,另有一个在世子女,在胎儿畸形扫描中被怀疑患有骨骼发育异常。出生时的临床表现包括身材矮小、长骨弯曲,下肢比上肢更受影响,严重的关节挛缩导致活动受限、发育不良、肌张力亢进以及食指屈曲畸形。婴儿期,该婴儿出现吸吮和吞咽困难,需要鼻饲喂养,并且反复出现呼吸窘迫发作,因呼吸衰竭频繁入院,需要重症监护并进行机械通气。骨骼检查显示长骨和脊柱发育异常。为了调查疑似遗传综合征,进行了全外显子组测序检测,结果在该基因中发现了一个新的纯合突变。
