Fetal anomalies v2.10 AP1S2 Arina Puzriakova Tag Q4_21_MOI was removed from gene: AP1S2.
Fetal anomalies v2.10 AP1S2 Arina Puzriakova commented on gene: AP1S2: The mode of inheritance of this gene has been updated to 'X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males)' following NHS Genomic Medicine Service approval.
Fetal anomalies v2.9 AP1S2 Arina Puzriakova Source NHS GMS was added to AP1S2.
Mode of inheritance for gene AP1S2 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)
Fetal anomalies v1.977 AP1S2 Arina Puzriakova changed review comment from: Comment on mode of inheritance: Review of literature did not reveal any confirmed affected females. Female carriers of AP1S2 variants are phenotypically normal and have mostly shown random X-inactivation. Huo et al., 2019 (PMID: 30714330) state that they identified a female patient (I-1) but this individual was not available for genetic testing and so it is unclear whether they harboured a variant on a one or both alleles.

As no confirmed female cases have been reported and the allelic requirement remains elusive, the MOI should be set to the default XL (i.e. monoallelic in females may cause disease) as this will ensure that both mono and biallelic variants are picked up in females by the pipeline.; to: Comment on mode of inheritance: Review of literature did not reveal any confirmed affected females.

As it is not known definitively whether females require a variant on each allele of this gene in order to be affected, the MOI should be set to the default XL (i.e. monoallelic in females may cause disease).
Fetal anomalies v1.730 AP1S2 Arina Puzriakova Tag Q4_21_MOI tag was added to gene: AP1S2.
Fetal anomalies v1.730 AP1S2 Arina Puzriakova Phenotypes for gene: AP1S2 were changed from MENTAL RETARDATION X-LINKED TYPE 59 to Pettigrew syndrome, OMIM:304340

Fetal anomalies v0.134 AP1S2 Rebecca Foulger edited their review of gene: AP1S2: Added comment: This gene and phenotype were reviewed during meetings at Great Ormond Street hospital in March 2019. Clinical review and curation was performed by Lyn Chitty, Anna de Burca, Rhiannon Mellis, Richard Scott, Ellen McDonagh and Rebecca Foulger. Outcome of review: Confirmed that phenotype is fetally-relevant: keep on the Fetal anomalies panel as a Green gene.; Changed rating: GREEN
