Rebecca Foulger Added comment: Comment on mode of inheritance: Changed Mode of inheritance from XLR to XLD: Alpha-thalassemia/mental retardation syndrome, 301040 is listed as XLD in OMIM (in addition to Mental retardation-hypotonic facies syndrome, X-linked, 309580 listed as XLR). Although PMID:17503331 report that nearly all female carriers of ATRX syndrome have highly skewed X-chromosome inactivation in favour of cells expressing the normal ATRX allele and are essentially phenotypically normal, PMID:16955409 report a female carrier where the chromosome carrying the mutant allele was active and she therefore showed a phenotype.
Rebecca Foulger Mode of inheritance for gene: ATRX was changed from X-LINKED: hemizygous mutation in males, biallelic mutations in females to X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males)
Rebecca Foulger Publications for gene: ATRX were set to 25529582; 24896178; 26860117; 26997013; 10995512; 7697714; 12116232; 15565397; 8644709; 9244431; 9598720
Rebecca Foulger commented on gene: ATRX: PMID:16955409: Badens et al. 2006 report a 4 year old female with a heterozygous R246C variant in ATRX and a skewed pattern of X-inactivation where her maternally-inherited X chromosome that carried the de novo variant remained active. Clinical features included severed DD.
