CC   -!- DISEASE: Linear skin defects with multiple congenital anomalies 1
CC       (LSDMCA1) [MIM:309801]: A disorder characterized by dermal, ocular,
CC       neurological and cardiac abnormalities. LSDMCA1 main features are
CC       unilateral or bilateral microphthalmia, linear skin defects in affected
CC       females, and in utero lethality for males. Skin defects are limited to
CC       the face and neck, consisting of areas of aplastic skin that heal with
CC       age to form hyperpigmented areas. Additional features in female
CC       patients include agenesis of the corpus callosum, sclerocornea,
CC       chorioretinal abnormalities, infantile seizures, congenital heart
CC       defect, intellectual disability, and diaphragmatic hernia.
CC       Microphthalmia is a disorder of eye formation, ranging from small size
CC       of a single eye to complete bilateral absence of ocular tissues
CC       (anophthalmia). In many cases, microphthalmia/anophthalmia occurs in
CC       association with syndromes that include non-ocular abnormalities.
CC       {ECO:0000269|PubMed:17033964}. Note=The disease is caused by variants
CC       affecting the gene represented in this entry.
CC   -!- SIMILARITY: Belongs to the cytochrome c-type heme lyase family.
CC       {ECO:0000305}.
