Stüve-Wiedemann Syndrome (STWS) is an autosomal recessive condition caused by variants in the LIFR gene, presenting with respiratory failure, hyperthermia and skeletal dysplasia in the neonatal period. Historically identified as a lethal condition, more children are now managed holistically from early in life with multidisciplinary team involvement with improved outcomes. This stems from early diagnosis, supported by molecular testing in the pre and postnatal periods. This report includes five such cases with survival in childhood to 10 years old in the UK affected by skeletal abnormalities, hyperthermia, respiratory distress and their diagnostic odyssey. All cases have a molecular diagnosis; two patients (family 1) were found to be homozygous for a novel pathogenic LIFR variant NM_002310.5:c.704G > A, p.(Trp235Ter). One patient (family 2) is compound heterozygous with the previously reported LIFR variant NM_002310.5:c.756dup p.(Lys253Ter), and a second novel variant NM_002310.5:c.397+5G > A. Two patients (family 3) are homozygous for one of the same LIFR variants NM_002310.5:c.756dup p.(Lys253Ter) as in family 2. This report discusses genotypic and phenotypic data for five patients with STWS, as well as the need for multi-disciplinary, proactive management and genetic counselling.
斯蒂夫-威德曼综合征(STWS)是一种常染色体隐性遗传病,由 LIFR 基因突变引起,新生儿期表现为呼吸衰竭、发热和骨骼发育不良。历史上被认为是一种致命疾病,现在更多的儿童从生命早期开始通过多学科团队的全面管理,通过早期诊断,在围产期进行分子检测,从而改善预后。本报告包括英国五例骨骼异常、发热、呼吸窘迫的患儿,其生存至 10 岁,他们的诊断历程曲折。所有病例均有分子诊断;两名患者(家族 1)为 LIFR 基因 NM_002310.5:c.704G>A,p.(Trp235Ter)纯合新致病性变异。一名患者(家族 2)为 LIFR 基因 NM_002310.5:c.756dup p.(Lys253Ter)复合杂合,另一个新变异 NM_002310.5:c.397+5G>A。两名患者(家族 3)为 LIFR 基因 NM_002310.5:c.756dup p.(Lys253Ter)纯合,与家族 2 中的相同变异相同。本报告讨论了 5 例 STWS 患者的基因型和表型数据,以及多学科、主动管理和遗传咨询的必要性。
