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]
LEPR Gene-Disease associations (from GenCC):
  • obesity due to leptin receptor gene deficiency

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.023051769).
BS1
Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.0000356 (52/1461728) while in subpopulation SAS AF = 0.000394 (34/86226). AF 95% confidence interval is 0.00029. There are 0 homozygotes in GnomAdExome4. There are 32 alleles in the male GnomAdExome4 subpopulation. Median coverage is 33. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The c.3253A>G (p.I1085V) alteration is located in exon 20 (coding exon 18) of the LEPR gene. This alteration results from a A to G substitution at nucleotide position 3253, causing the isoleucine (I) at amino acid position 1085 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
