Mild growth retardation and developmental delay, microcephaly, and a distinctive facial appearance
1Newcastle and Northern New South Wales Genetics Service, Australia.
Insights
A new genetic syndrome causes growth deficiency, developmental delay, and distinct facial features. This condition, likely autosomal recessive, affects multiple family members and unrelated individuals.
Area of Science:
- Genetics
- Pediatrics
- Clinical Medicine
Background:
- Genetic disorders can manifest with a range of developmental and physical abnormalities.
- Syndromic conditions often present with a constellation of unique clinical features.
Observation:
- Three unrelated individuals (a brother-sister pair and a girl) presented with pre- and post-natal growth deficiency.
- Key features included developmental delay, microcephaly, and a characteristic facial appearance (thick eyebrows, full cheeks, short nose).
- A notably friendly personality was observed in affected individuals.
Findings:
- The described symptoms suggest a novel genetic syndrome.
- The pattern of inheritance appears to be autosomal recessive, based on affected family members.
Implications:
- Identification of this new syndrome aids in genetic diagnosis and counseling.
- Further research can elucidate the specific gene(s) and molecular mechanisms underlying this condition.
- Understanding this syndrome contributes to the broader knowledge of human genetic disorders.
Abstract:
We describe a brother and sister from one family and a girl from a second, unrelated family; they have a syndrome of pre- and post-natal growth deficiency, developmental delay, a friendly personality, microcephaly, and a distinctive facial appearance marked by thick eyebrows, full cheeks, and a short nose with the columella inserted below the nasal alae. We think this is a new syndrome probably inherited as an autosomal recessive trait.
