OMIM : ⁵⁶ Autosomal recessive cutis laxa type II represents a spectrum of clinical entities with variable severity of cutis laxa, abnormal growth, developmental delay, and associated skeletal abnormalities. Aside from cutis laxa, persistent wide fontanels, frontal bossing, slight oxycephaly, downward-slanted palpebral fissures, reversed-V eyebrows, and dental caries are characteristic. Patients with ARCL2 can be divided into 2 major groups: ARCL2A, comprising those with a combined N- and O-linked glycosylation defect (CDG type II), and ARCL2B, those without a metabolic disorder (summary by Morava et al., 2009). Van Maldergem et al. (2008) concluded that ARCL2A should be considered more of a multisystem disorder with cobblestone-like brain dysgenesis manifesting as developmental delay and an epileptic neurodegenerative syndrome rather than purely a dermatologic disorder. For a phenotypic description and a discussion of genetic heterogeneity of autosomal recessive cutis laxa, see ARCL1A (219100). (219200)

MalaCards based summary : Cutis Laxa, Autosomal Recessive, Type Iia, also known as cutis laxa with joint laxity and retarded development, is related to cutis laxa, autosomal dominant 1 and cutis laxa, autosomal recessive, type ia, and has symptoms including seizures An important gene associated with Cutis Laxa, Autosomal Recessive, Type Iia is ATP6V0A2 (ATPase H+ Transporting V0 Subunit A2), and among its related pathways/superpathways are Arginine and proline metabolism and Amino acid synthesis and interconversion (transamination). Affiliated tissues include skin, brain and eye, and related phenotypes are intellectual disability and inguinal hernia

Disease Ontology : ¹² An autosomal recessive cutis laxa type II classic type that has material basis in homozygous or compound heterozygous mutations in the ATP6V0A2 gene on chromosome 12q24.

UniProtKB/Swiss-Prot : ⁷³ Cutis laxa, autosomal recessive, 2A: A disorder characterized by an excessive congenital skin wrinkling, a large fontanelle with delayed closure, a typical facial appearance with downslanting palpebral fissures, a general connective tissue weakness, and varying degrees of growth and developmental delay and neurological abnormalities. Some affected individuals develop seizures and mental deterioration later in life, whereas the skin phenotype tends to become milder with age. At the molecular level, an abnormal glycosylation of serum proteins is observed in many cases.
