Variant summary

Our verdict is Benign. Variant got -10 ACMG points: 0P and 10B. BP4_Strong BP6_Moderate BS2

The NM_004797.4(ADIPOQ):c.662G>A(p.Arg221His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000198 in 1,614,026 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R221S) has been classified as Likely benign.

Genes affected

ADIPOQ (HGNC:13633): (adiponectin, C1Q and collagen domain containing) This gene is expressed in adipose tissue exclusively. It encodes a protein with similarity to collagens X and VIII and complement factor C1q. The encoded protein circulates in the plasma and is involved with metabolic and hormonal processes. Mutations in this gene are associated with adiponectin deficiency. Multiple alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Apr 2010]

ADIPOQ-AS1 (HGNC:40648): (ADIPOQ antisense RNA 1)

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.031370223).
• BP6: Variant 3-186854631-G-A is Benign according to our data. Variant chr3-186854631-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 2216533.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS2: High AC in GnomAd at 10 AD gene.

Ambry Genetics

Jun 23, 2021

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
