Stephanie Allen (Birmingham Women's NHS Foundation Trust)

Green List (high evidence)

This gene and phenotype were reviewed during meetings in June & July 2025. The meetings included representatives of the North Thames and Central & South R21 testing GLHs and from the R21 Clinical Oversight Group. Clinical review and curation was performed by Natalie Chandler & Elizabeth Scotchman (North Thames GLH), Natalie Bibb, Stephanie Allen & Sarah Graham (Central & South GLH) and Alice Gardham, Esther Kinning, Vicki Harrison, Anna DeBurca, Natalie Canham, Elizabeth Wall, Sunayna Best, Soo-Mi Park & Sahar Mansour (R21 Clinical Oversight Group).

Panel Version: 6.28
38723631: 20 individuals with rare PPFIA3 variants (19 heterozygous and 1 compound heterozygous) presenting with developmental delay, intellectual disability, hypotonia, dysmorphisms, microcephaly or macrocephaly, autistic features, and epilepsy with reduced penetrance. Individual abnormalities include anal atresia, absent bladder, dysmorphisms, prenatal diagnosis of abnormal gyration and ventriculomegaly, brain MRI anomalies, Dysmorphic facial features were described in 13 individuals, which included prominent forehead, plagiocephaly, triangular face, clinodactyly, strabismus, wide mouth, widely spaced teeth, and bilateral epicanthal folds Macrocephaly or microcephaly were present in nine individuals. There are also several other papers. Suggest green
