Genes affected
AGRP (HGNC:330): (agouti related neuropeptide) This gene encodes an antagonist of the melanocortin-3 and melanocortin-4 receptor. It appears to regulate hypothalamic control of feeding behavior via melanocortin receptor and/or intracellular calcium regulation, and thus plays a role in weight homeostasis. Mutations in this gene have been associated with late on-set obesity. [provided by RefSeq, Dec 2009]
ATP6V0D1-DT (HGNC:55268): (ATP6V0D1 divergent transcript)

The AGRP p.Val88Val variant was not identified in the literature nor was it identified in ClinVar, Cosmic or LOVD 3.0. The variant was identified in dbSNP (ID: rs145840661) and in control databases in 26 of 282604 chromosomes at a frequency of 0.000092 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: African in 25 of 24936 chromosomes (freq: 0.001003) and Latino in 1 of 35430 chromosomes (freq: 0.000028); it was not observed in the Ashkenazi Jewish, East Asian, European (Finnish), European (non-Finnish), Other or South Asian populations. The p.Val88Val variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. The variant occurs outside of the splicing consensus sequence and 2 of 4 in silico or computational prediction software programs (MaxEntScan, NNSPLICE) predict a greater than 10% difference in splicing; this is not very predictive of pathogenicity. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -
