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. [provided by RefSeq, Jan 2010]
MC4R Gene-Disease associations (from GenCC):
  • inherited obesity
    Inheritance: AD Classification: STRONG Submitted by: Laboratory for Molecular Medicine
  • obesity due to melanocortin 4 receptor deficiency
    Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

PM1
In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 12 uncertain in NM_005912.3
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.
BP4
Computational evidence support a benign effect (MetaRNN=0.09116614).
BS2
High AC in GnomAdExome4 at 15 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
