Cutis laxa, autosomal recessive, type 1A- MedGen UID:

- Disease or Syndrome
FBLN5-related cutis laxa is characterized by cutis laxa, early childhood-onset pulmonary emphysema, peripheral pulmonary artery stenosis, and other evidence of a generalized connective disorder such as inguinal hernias and hollow viscus diverticula (e.g., intestine, bladder). Occasionally, supravalvar aortic stenosis is observed. Intrafamilial variability in age of onset is observed. Cardiorespiratory failure from complications of pulmonary emphysema (respiratory or cardiac insufficiency) is the most common cause of death.

- Disease or Syndrome
The phenotype of autosomal recessive cutis laxa type II (ARCL2) includes cutis laxa of variable severity, abnormal growth, developmental delay, and associated skeletal abnormalities (summary by Morava et al., 2009). No specific clinical features distinguish ARCL2A (219200), which includes a glycosylation defect, and ARCL2B, in which abnormal glycosylation has not been reported (Morava et al., 2009; Guernsey et al., 2009).

- Disease or Syndrome
Autosomal recessive cutis laxa type IIE (ARCL2E) is characterized by connective tissue features, including generalized cutis laxa and inguinal hernia, craniofacial dysmorphology, variable mild heart defects, and prominent skeletal features, including craniosynostosis, short stature, brachydactyly, clinodactyly, and syndactyly (Pottie et al., 2021).
