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]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP6: Variant 1-65565843-T-TCA is Benign according to our data. Variant chr1-65565843-T-TCA is described in ClinVar as [Likely_benign]. Clinvar id is 1187101.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.016 (2401/150368) while in subpopulation AFR AF= 0.03 (1227/40866). AF 95% confidence interval is 0.0286. There are 33 homozygotes in gnomad4. There are 1192 alleles in male gnomad4 subpopulation. Median coverage is 11. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 33 AR gene
