Genes affected

CA2 (HGNC:1373): (carbonic anhydrase 2) The protein encoded by this gene is one of several isozymes of carbonic anhydrase, which catalyzes reversible hydration of carbon dioxide. Defects in this enzyme are associated with osteopetrosis and renal tubular acidosis. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jun 2014]

CA3-AS1 (HGNC:51657): (CA3 antisense RNA 1)

ACMG classification

Our verdict: Likely_benign. The variant received -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.76).
• BP6: Variant 8-85464133-C-A is Benign according to our data. Variant chr8-85464133-C-A is described in ClinVar as Likely_benign. ClinVar VariationId is 2772709.Status of the report is criteria_provided_single_submitter, 1 stars.
