Familial Woolly Hair

Area of Science:

• Dermatology
• Genetics
• Pediatrics

Background:

• Congenital woolly hair is a rare genetic disorder affecting hair shaft structure, presenting as tightly curled hair.
• It has two main forms: autosomal dominant hereditary woolly hair and the rarer autosomal recessive familial woolly hair.
• Associated conditions include keratosis pilaris, nail dystrophy, and certain syndromes like Naxos disease.

Purpose of the Study:

• To report a rare case of congenital woolly hair in multiple siblings from an Indian family.
• To describe the clinical presentation and spectrum of this condition.
• To emphasize the need for further genetic investigation into its molecular basis.

Main Methods:

• Clinical examination of a 10-year-old female with persistent hair abnormalities since birth.
• Detailed assessment of hair shaft characteristics (tightly coiled, sparse, light-colored).
• Evaluation of associated features, including eyebrow hair loss.

Main Results:

• The patient presented with persistently short, sparse, and tightly coiled scalp hair and partial eyebrow loss.
• The affected siblings suggest a familial pattern, possibly autosomal recessive.
• The case expands the understanding of congenital woolly hair's clinical manifestations in an Indian population.

Conclusions:

• Congenital woolly hair presents with distinct hair shaft abnormalities and can have associated features.
• Familial occurrence in this case suggests a genetic basis requiring further molecular investigation.
• This case highlights the clinical variability and importance of recognizing this rare disorder.
