Targeted syndrom under study

ABCA2 (OMIM # 618808)


Intellectual developmental disorder with poor growth and with or without seizures or ataxia (IDPOGSA) is caused by homozygous mutation in the ABCA2 gene (600047) on chromosome 9q34 and has a highly variable phenotype. We suspect that both bi- and monoallelic variants in ABCA2 can cause clinical problems (developmental delay, intellectual disability, seizures, abnormality of coordination, ataxia, autistic features). We hope to identify further individuals with ABCA2 variants to better define its phenotypic spectrum and phenotype-genotype correlation.
