Green List (high evidence)

Biallelic NALCN variants cause severe infantile hypotonia with psychomotor retardation and characteristic facial features. Microcephaly a reported feature.


NB: Not within the scope of Prepair+ testing, but monoallelic NALCN missense variants are associated with congenital contractures of the limbs and face, hypotonia, and developmental delay (MIM#616266) (PMID: 25683120). Affected individuals present with congenital contractures of the limbs and face, hypotonia, and developmental delay. Common features include clubfoot and camptodactyly of the digits of the hands and ulnar deviation of the wrist.
