Variable clinical presentation of cutis laxa
Insights
Congenital cutis laxa affects four males across two families, presenting with varied symptoms like developmental delay and ligamentous laxity. Under-diagnosis is a risk due to subtle skin laxity in some patients.
Area of Science:
- Genetics
- Dermatology
- Pediatrics
Background:
- Congenital cutis laxa (CCL) is a rare connective tissue disorder characterized by generalized skin laxity.
- The genetic basis and inheritance patterns of CCL are complex and not fully understood.
- Accurate diagnosis is crucial for patient management and genetic counseling.
Observation:
- This study reports on two families (Family A and Family B) with a total of four affected males with congenital cutis laxa.
- Family A includes a single affected male with developmental delay and ligamentous laxity.
- Family B includes three affected males, two with significant systemic involvement, and one with less apparent skin laxity.
Findings:
- The presentation of congenital cutis laxa in males can be variable, with some exhibiting subtle skin findings.
- The second reported male patient with this specific syndrome highlights its rarity in males.
- Recessive inheritance is suggested in Family B, while the inheritance pattern in Family A remains inconclusive.
Implications:
- Subtle clinical features, such as mild skin laxity, can lead to under-diagnosis of congenital cutis laxa.
- Recognizing the diverse clinical spectrum is essential for timely diagnosis and intervention.
- Further research is needed to elucidate the genetic underpinnings and inheritance patterns of CCL in affected families.
Abstract:
We present 2 families with 4 individuals suffering from congenital cutis laxa. Family A has a single affected male child with developmental delay and ligamentous laxity, making this only the second male of the total 15 patients so far reported with this particular syndrome. Family B has 3 affected males, 2 of whom have significant involvement of other systems. Only one of the 4 affected children had very obvious loose skin folds and dependency on this clinical feature alone could result in under-diagnosis of this disease. The clinical features and family pedigree information suggests recessive inheritance in Family B but the mode of inheritance in Family A is inconclusive.
