Microphthalmia, Lenz type

What it is

A rare X-linked inherited form of syndromic microphthalmia characterized by unilateral or bilateral microphthalmia (and/or clinical anophthalmia) with or without coloboma in addition to a range of extraocular manifestations such as microcephaly, malformed ears, dental abnormalities (i.e. irregular shape of incisors), skeletal anomalies (duplicated thumbs, syndactyly, clinodactyly, camptodactyly), urogenital anomalies (hypospadias, cryptorchidism, renal dysgenesis, hydroureter) and mild to severe intellectual disability. It is allelic to two disorders: oculofaciocardiodental syndrome and premature aging appearance-developmental delay-cardiac arrhythmia syndrome.

Signs and symptoms

These ranges are how often a sign appears across everyone diagnosed, not a prediction for one person — most people have some of these and not others. Orphanet also records findings that are specifically absent in this disease; those are in the data but not listed here.

ICD-10 codes

ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
