Anonychia Congenita - Rare Inheritance of a Rare Disorder.

Non syndromic Anonychia congenita or congenital absence of finger and toe nails is a rare disorder known to occur due to autosomal recessive inheritance of mutation in the R-spondin-4 gene. We present a case of a 32 year old female born of a non-consanguineous marriage presenting with complete absence of finger and toe nails since birth and similar presentation in family members over four generations, suggesting an autosomal dominant inheritance.
