This gene and phenotype were reviewed during meetings between November 2024 & January 2025. The meetings included representatives of the Central & South and North Thames R21 testing GLHs and from the R21 Clinical Oversight Group. Clinical review and curation was performed by Stephanie Allen, Natalie Bibb, and Sarah Graham (Central & South GLH), Natalie Chandler and Elizabeth Scotchman (North Thames GLH), and Sunayna Best, Anna De Burca, Natalie Canham, Samantha Doyle, Alice Gardham, Victoria Harrison, Esther Kinning, Sahar Mansour, Soo-Mi Park, and Elizabeth Wall (R21 Clinical Oversight Group).

Amber on Australian fetal anomalies panel. 35 individuals from 33 unrelated families reported with heterozygous variants in this gene. Macrocephaly in most individuals, otherwise no significant association with congenital anomalies. PMID: 30397230 only prenatal phenotype would be macrocephaly (seen in 58%).
