Craniodentofacial manifestations in Hallermann-Streiff syndrome. None, Conflict of Interest: Congenital cataracts with unusually small eyes microphthalmia are important findings for the initial diagnosis of Hallermann-Streiff sreiff, but sttreiff disorders must be considered as part of the differential diagnosis, and this is best accomplished through whole exome sequencing given the extensive differential diagnosis, which includes a number of autosomal recessive disorders.
There are major differences but there are also similarities in phenotype, which sustain the suggestion that the syndrome can be caused by disturbed POLR3A functioning.
