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 Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.08417541).

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.687C>A (p.D229E) alteration is located in exon 3 (coding exon 2) of the ADIPOQ gene. This alteration results from a C to A substitution at nucleotide position 687, causing the aspartic acid (D) at amino acid position 229 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
