Microcephaly albinism digital anomalies syndrome

X-ray of a patient with microcephaly albinisim digital anomalies syndrome.^[1]

Microcephaly albinism digital anomalies syndrome is a very rare congenital genetic disease. The syndrome includes microcephaly, micrognathia, oculocutaneous albinism, hypoplasia of the distal phalanx of fingers, and agenesia of the distal end of the right big toe.^[2]

Symptoms and signs[]

Microcephaly albinism digital anomalies syndrome's symptoms may vary from individual to individual, however there are many common symptoms, associated with this rare genetic disease. Common symptoms are:^[2]

microcephaly
oculocutaneous albinism
Slow development of the fingers
hypoplasia of the distal phalanx of fingers
tyrosinase‐positive oculocutaneous albinism
Recurrent bacterial infections
granulocytopenia
intermittent thrombopenia
protruding midface/dysmorphism
rough and projecting hair
mild mental retardation^[3]

Genetics[]

In males, duplication of a portion of Xq chromosome is associated with multiple congenital anomalies and developmental delay. Most females recognized as having dup(Xq) chromosomes are phenotypically apparently normal relatives of phenotypically abnormal males. The disease also is associated with the inactivation of the duplicated X chromosomes.^{[citation needed]}
