Congenital atrichia with papular lesions is a rare, autosomal recessive and irreversible form of total alopecia of the body hair characterized by hair loss soon after birth and the development of keratinfilled cysts or horny papules over extensive areas of the body. The condition is associated with a mutation of the human hairless gene on chromosome region 8p12. We report a 1-year-old boy presenting with the absence of scalp and body hair since birth. On examination, he had complete absence of hair on the scalp, eyebrows, and eyelashes. Multiple, discrete, pearly-to-skin-colored papules of 1-3mm in size were present over the scalp. The skin biopsy from a scalp papule revealed normal overlying epidermis with multiple keratin cysts and hypoplastic hair follicles in the upper dermis.

Congenital atrichia a rare form of alopecia in children, presents with complete absence or sparse hair over the scalp and body, while the teeth, nails, and sweat glands are normal. Uncommonly, this hair abnormality can be associated with any systemic or cutaneous abnormalities. We report three cases of congenital atrichia with parental nonconsanguinity and central nervous associations such as developmental delay,spastic quadriparesis, failure to thrive, myoclonic seizures, and attention deficit hyperactivity disorder.

An uncommon disorder known as atrichia congenita with ectodermal defects (isolated type) can present with the complete absence of hair at birth or can cause the scalp hair to fall out between the ages of one to six months, after that no new hair growth occurs. Patients don't develop pubic and axillary hairs in addition to lacking or having scant brow, eyelash, and body hair. It could develop independently or in tandem with other problems.

Variants in genes encoding core components of the spliceosomes are associated with craniofacial syndromes, collectively called craniofacial spliceosomopathies. SNRPE encodes a core component of pre-mRNA processing U-rich small nuclear ribonuclear proteins (UsnRNPs). Heterozygous variants in SNRPE have been reported in six families with isolated hypotrichosis simplex in addition to one case of isolated non syndromic congenital microcephaly.

Background: Skin lesions on the feet and foot deformities impair daily activities and decrease quality of life. Although substantial foot deformities occur in many genodermatoses, few reports have been published on this topic. Therefore, we performed a retrospective chart review to identify patients with genodermatoses and foot disorders.
