Green List (high evidence)

The DDG2P confidence category for the disease CLOVES: CONGENITAL LIPOMATOUS OVERGROWTH, VASCULAR MALFORMATIONS, AND EPIDERMAL NEVI, OMIM:612918 is definitive. The allelic requirement, mutation consequence and cross cutting modifier are monoallelic_autosomal, altered gene product structure and typically mosaic respectively (PMID:22658544).

The DDG2P confidence category for the disease MEGALENCEPHALY-CAPILLARY MALFORMATION-POLYMICROGYRIA SYNDROME, SOMATIC 3, OMIM:602501 is definitive. The allelic requirement, mutation consequence and cross cutting modifier are monoallelic_autosomal, altered gene product structure and typically mosaic respectively (PMID:22729224).

The DDG2P confidence category for the disease HEMIMEGALENCEPHALY PIK3CA is definitive. The allelic requirement, mutation consequence and cross cutting modifier are monoallelic_autosomal, altered gene product structure and typically mosaic respectively.
