Fetal anomalies v4.146 MYBPC3 Achchuthan Shanmugasundram Phenotypes for gene: MYBPC3 were changed from ?Congenital myopathy; Cardiomyopathy; Cardiomyopathy, hypertrophic, 4, OMIM:115197 to Cardiomyopathy, hypertrophic, 4, OMIM:115197
Fetal anomalies v4.36 MYBPC3 Achchuthan Shanmugasundram commented on gene: MYBPC3
Fetal anomalies v4.35 MYBPC3 Esther Kinning reviewed gene: MYBPC3: Rating: AMBER; Mode of pathogenicity: ; Publications: 19858127, 16679492, 17937428; Phenotypes: Cardiomyopathy, hypertrophic, 4, OMIM:115197, Neonatal hypertrophic cardiomyopathy; Mode of inheritance: BIALLELIC, autosomal or pseudoautosomal
Fetal anomalies v4.34 MYBPC3 Achchuthan Shanmugasundram Source NHS GMS was added to MYBPC3.
Mode of inheritance for gene MYBPC3 was changed from BOTH monoallelic and biallelic (but BIALLELIC mutations cause a more SEVERE disease form), autosomal or pseudoautosomal to BIALLELIC, autosomal or pseudoautosomal
Added phenotypes Cardiomyopathy, hypertrophic, 4, OMIM:115197 for gene: MYBPC3
Publications for gene: MYBPC3 were updated from 19858127; 28749478 to 19858127; 16679492; 28749478; 17937428
Fetal anomalies v1.945 MYBPC3 Arina Puzriakova Classified gene: MYBPC3 as Amber List (moderate evidence)
Fetal anomalies v1.945 MYBPC3 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.

Note that the two fetal cases reported in literature harboured homozygous variants (PMID:19858127; 28749478) although expert reviewer suggests an MOI of 'both mono- and biallelic'
Fetal anomalies v1.945 MYBPC3 Arina Puzriakova Gene: mybpc3 has been classified as Amber List (Moderate Evidence).
Fetal anomalies v1.944 MYBPC3 Arina Puzriakova Publications for gene: MYBPC3 were set to PMID: 28749478; 19858127
Fetal anomalies v1.900 MYBPC3 Rhiannon Mellis gene: MYBPC3 was added
gene: MYBPC3 was added to Fetal anomalies. Sources: Expert Review,Literature
Mode of inheritance for gene: MYBPC3 was set to BOTH monoallelic and biallelic (but BIALLELIC mutations cause a more SEVERE disease form), autosomal or pseudoautosomal
Publications for gene: MYBPC3 were set to PMID: 28749478; 19858127
Phenotypes for gene: MYBPC3 were set to Cardiomyopathy; ?Congenital myopathy
Review for gene: MYBPC3 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 pending more evidence.

Currently rated Green on the following other PanelApp panel(s): Various cardiomyopathy panels. Amber on congenital myopathy panel.

Details of review:
Previously only one (AR) case with skeletal muscle phenotype, although is a known cardiomyopathy gene (PMID: 19858127). One fetal case reported by Shamseldin et al 2018 (PMID: 28749478) with hydrops.
