Lethal multiple pterygium syndrome (LMPS) is a rare disease with genetic and phenotypic heterogeneity and is inherited in an autosomal recessive (AR) pattern. Here, we have presented clinically significant results describing two novel mutations of gene: NM_000751.2: c.1006C>T p.(Arg336Ter) and NM_000751.2:c.973_975delGTG p.(Val325del), and measurement of the facial angle for determining micrognathia by prenatal diagnosis in the first trimester of pregnancy for a Lethal multiple pterygium syndrome case. In conclusion, this report complements the spectrum of genetic variants and phenotype of Lethal multiple pterygium syndrome and provides reliable recommendation for the counseling of future pregnancies in families with the disease.
致死性多发性翼状胬肉综合征(LMPS)是一种罕见疾病,具有遗传和表型异质性,以常染色体隐性(AR)模式遗传。在此,我们展示了具有临床意义的结果,描述了一个基因的两个新突变:NM_000751.2:c.1006C>T p.(Arg336Ter)和NM_000751.2:c.973_975delGTG p.(Val325del),并对一例致死性多发性翼状胬肉综合征病例在妊娠早期通过产前诊断测量面部角度以确定小颌畸形。总之,本报告补充了致死性多发性翼状胬肉综合征的遗传变异和表型谱,并为该病家庭未来妊娠的咨询提供了可靠建议。
