Mendeliome v1.2928 PPP1R2 Zornitza Stark gene: PPP1R2 was added
gene: PPP1R2 was added to Mendeliome. Sources: Literature
Mode of inheritance for gene: PPP1R2 was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: PPP1R2 were set to 40597352; 26558779
Phenotypes for gene: PPP1R2 were set to Neurodevelopmental disorder, PPP1R2-related
Review for gene: PPP1R2 was set to RED
Added comment: Single individual reported with homozygous splicing variant c.403 + 3 A >T. Abnormal splicing demonstrated but leaky. Clinical features included pre and postnatal growth restriction, ventricular septal defect, dysmorphic features (proptosis, long eye lashes, thick eyebrows, low-set ears), microcephaly, sensorineural hearing loss, cortical cataracts, retinal defects, intellectual disability with limited speech, and autism spectrum disorder. Note mouse model is embryonically lethal, leading the authors to speculate survival may be due to fraction of normally spliced transcripts.
