Genes affected

LEP (HGNC:6553): (leptin) This gene encodes a protein that is secreted by white adipocytes into the circulation and plays a major role in the regulation of energy homeostasis. Circulating leptin binds to the leptin receptor in the brain, which activates downstream signaling pathways that inhibit feeding and promote energy expenditure. This protein also has several endocrine functions, and is involved in the regulation of immune and inflammatory responses, hematopoiesis, angiogenesis, reproduction, bone formation and wound healing. Mutations in this gene and its regulatory regions cause severe obesity and morbid obesity with hypogonadism in human patients. A mutation in this gene has also been linked to type 2 diabetes mellitus development. [provided by RefSeq, Aug 2017]

ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 9 ACMG points.

PM1

In a chain Leptin (size 145) in uniprot entity LEP_HUMAN there are 6 pathogenic changes around while only 1 benign (86%) in NM_000230.3

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 6 curated pathogenic missense variants (we use a threshold of 10). The gene has 1 curated benign missense variants. Gene score misZ: 0.90973 (below the threshold of 3.09). Trascript score misZ: 1.8247 (below the threshold of 3.09). GenCC associations: The gene is linked to obesity due to congenital leptin deficiency.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.91

PP5

Variant 7-128254568-C-A is Pathogenic according to our data. Variant chr7-128254568-C-A is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 2735087.Status of the report is criteria_provided_single_submitter, 1 stars.
