Genes affected

MC4R (HGNC:6932): (melanocortin 4 receptor) The protein encoded by this gene is a membrane-bound receptor and member of the melanocortin receptor family. The encoded protein interacts with adrenocorticotropic and MSH hormones and is mediated by G proteins. This is an intronless gene. Defects in this gene are a cause of autosomal dominant obesity.

ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 7 ACMG points.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 29 curated pathogenic missense variants (we use a threshold of 10). The gene has 3 curated benign missense variants. Gene score misZ: -1.0099 (below the threshold of 3.09). Trascript score misZ: 0.30396 (below the threshold of 3.09). GenCC associations: The gene is linked to obesity due to melanocortin 4 receptor deficiency, inherited obesity.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.938

PP5

Variant 18-60371403-A-C is Pathogenic according to our data. Variant chr18-60371403-A-C is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 14331.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS2

High AC in GnomAdExome4 at 23 AD gene.
