Associated with phenotype in OMIM, and a probable gene for PPP1R12A-related Holoprosencephaly Spectrum and Urogenital Malformations in G2P.
PMID: 31883643 (2020) - Screening cohorts of patients with holoprosencephaly and patients with disorders of sex development revealed 12 unrelated individuals with de novo LoF variants in the PPP1R12A gene. Variants were associated with a broad spectrum of manifestations, and a clear genotype-phenotype correlation was not observed - most commonly presentation included either malformations of the brain or the genitourinary tract (two individuals exhibited both brain and genitourinary anomalies). Out of the 12 patients, 4 were XY females and 3 were XY males with significant anomalies.
