Genes affected
LEPR (HGNC:6554): (leptin receptor) The protein encoded by this gene belongs to the gp130 family of cytokine receptors that are known to stimulate gene transcription via activation of cytosolic STAT proteins. This protein is a receptor for leptin (an adipocyte-specific hormone that regulates body weight), and is involved in the regulation of fat metabolism, as well as in a novel hematopoietic pathway that is required for normal lymphopoiesis. Mutations in this gene have been associated with obesity and pituitary dysfunction. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. It is noteworthy that this gene and LEPROT gene (GeneID:54741) share the same promoter and the first 2 exons, however, encode distinct proteins (PMID:9207021).[provided by RefSeq, Nov 2010]

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Aug 22, 2022 | For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 421140). This premature translational stop signal has been observed in individual(s) with severe early-onset obesity (PMID: 17229951). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Trp31*) in the LEPR gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in LEPR are known to be pathogenic (PMID: 23616257, 24319006, 25751111). - |
