Genes affected

METRNL (HGNC:27584): (meteorin like, glial cell differentiation regulator) Predicted to enable hormone activity. Predicted to be involved in several processes, including brown fat cell differentiation; energy homeostasis; and positive regulation of brown fat cell differentiation. Located in extracellular exosome. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0035634637).
• BP6: Variant 17-83085192-A-G is Benign according to our data. Variant chr17-83085192-A-G is described in ClinVar as [Benign]. Clinvar id is 768924.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0127 (1940/152312) while in subpopulation AFR AF= 0.0435 (1806/41564). AF 95% confidence interval is 0.0418. There are 49 homozygotes in gnomad4. There are 923 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
