Fetal anomalies v1.926 CHRM3 Arina Puzriakova Publications for gene: CHRM3 were set to 22077972; 31441039; 10944224
Fetal anomalies v1.925 CHRM3 Arina Puzriakova Classified gene: CHRM3 as Amber List (moderate evidence)
Fetal anomalies v1.925 CHRM3 Arina Puzriakova Added comment: Comment on list classification: New gene added to this panel by Rhiannon Mellis (GOSH). Rating Amber inline with this review, awaiting further evidence supporting that this gene can cause a fetal phenotype.
Fetal anomalies v1.925 CHRM3 Arina Puzriakova Gene: chrm3 has been classified as Amber List (Moderate Evidence).
Fetal anomalies v1.924 CHRM3 Arina Puzriakova Phenotypes for gene: CHRM3 were changed from Prune belly syndrome; Megacystis to Prune belly syndrome, OMIM:100100; Megacystis
Fetal anomalies v1.923 CHRM3 Arina Puzriakova Publications for gene: CHRM3 were set to PMID: 22077972; 31441039; 10944224
Fetal anomalies v1.900 CHRM3 Rhiannon Mellis gene: CHRM3 was added
gene: CHRM3 was added to Fetal anomalies. Sources: Expert Review,Literature
Mode of inheritance for gene: CHRM3 was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: CHRM3 were set to PMID: 22077972; 31441039; 10944224
Phenotypes for gene: CHRM3 were set to Prune belly syndrome; Megacystis
Review for gene: CHRM3 was set to AMBER
Added comment: This gene and phenotype were reviewed during a meeting on 21st October 2021 between representatives of the North Thames and Central & South R21 testing GLHs.

Clinical review and curation was performed by Lyn Chitty, Alison Male, Rowenna Roberts, Rhiannon Mellis (North Thames GLH) and Stephanie Allen, Denise Williams and Esther Kinning (Central & South GLH).

Outcome of review: May be fetally relevant but currently limited evidence, support adding to the Fetal anomalies panel as Amber gene.

Details of review:
Discussed as a potential cause of megacystis. Currently Red on Panelapp CAKUT panel (2016) because at that time there was only 1 reported family and a mouse model. The unpublished data mentioned in that panelapp review (from Adrian Woolf, Manchester) is now published so now 2 families PMID: 22077972; 31441039 plus a mouse model PMID: 10944224. However, prenatal findings (distended bladder and unilateral hydronephrosis) only documented for one individual. More evidence of prenatal phenotype would be helpful.
