NIH Rare Diseases : ⁵³ Microphthalmia with linear skin defects syndrome(MLS syndrome) is a genetic condition that affects the eyes and skin. It is mainly found in females and is characterized by small or poorly developed eyes (microphthalmia) and characteristic linear skin markings on the head and neck. The signs and symptoms of this condition may include abnormalities of the brain, heart, and genitourinary system. Other symptoms may include short stature, developmental delay, and finger and toenails that do not grow normally (nail dystrophy). MLS syndrome is typically caused by either a deletion of certain genetic material on the p (short) arm of the X chromosome or by a mutation in the HCCS gene. In some cases, it may be caused by mutations in the COX7B and NDUFB11 genes, (also located on the X chromosome). According to the mutated gene, the disease may be classified in three subtypes. This condition is inherited in an X-linked manner and is thought to result in serious early developmental concerns in males, leading to almost no males with this condition surviving to delivery. Although there is no specific treatment or cure for MLS syndrome, there may be ways to manage the symptoms. A team of doctors is often needed to figure out the treatment options based on each person’s symptoms.

MalaCards based summary : Linear Skin Defects with Multiple Congenital Anomalies 1, also known as midas syndrome, is related to mucolipidosis iii alpha/beta and mucolipidosis ii alpha/beta. An important gene associated with Linear Skin Defects with Multiple Congenital Anomalies 1 is HCCS (Holocytochrome C Synthase), and among its related pathways/superpathways is Oxidative phosphorylation. Affiliated tissues include skin, eye and heart, and related phenotypes are agenesis of corpus callosum and hydrocephalus

Genetics Home Reference : ²⁵ Microphthalmia with linear skin defects syndrome is a disorder that mainly affects females. In people with this condition, one or both eyes may be very small or poorly developed (microphthalmia). Affected individuals also typically have unusual linear skin markings on the head and neck. These markings follow the paths along which cells migrate as the skin develops before birth (lines of Blaschko). The skin defects generally improve over time and leave variable degrees of scarring.

OMIM : ⁵⁷ The microphthalmia with linear skin defects syndrome (MLS) is an X-linked dominant disorder characterized by unilateral or bilateral microphthalmia and linear skin defects--which are limited to the face and neck, consisting of areas of aplastic skin that heal with age to form hyperpigmented areas--in affected females and in utero lethality for males (Wimplinger et al., 2006).

UniProtKB/Swiss-Prot : ⁷⁵ Linear skin defects with multiple congenital anomalies 1: A disorder characterized by dermal, ocular, neurological and cardiac abnormalities. LSDMCA1 main features are unilateral or bilateral microphthalmia, linear skin defects in affected females, and in utero lethality for males. Skin defects are limited to the face and neck, consisting of areas of aplastic skin that heal with age to form hyperpigmented areas. Additional features in female patients include agenesis of the corpus callosum, sclerocornea, chorioretinal abnormalities, infantile seizures, congenital heart defect, mental retardation, and diaphragmatic hernia. Microphthalmia is a disorder of eye formation, ranging from small size of a single eye to complete bilateral absence of ocular tissues (anophthalmia). In many cases, microphthalmia/anophthalmia occurs in association with syndromes that include non-ocular abnormalities.
