Genes affected
CA11 (HGNC:1370): (carbonic anhydrase 11) Carbonic anhydrases (CAs) are a large family of zinc metalloenzymes that catalyze the reversible hydration of carbon dioxide. They participate in a variety of biological processes, including respiration, calcification, acid-base balance, bone resorption, and the formation of aqueous humor, cerebrospinal fluid, saliva, and gastric acid. They show extensive diversity in tissue distribution and in their subcellular localization. CA XI is likely a secreted protein, however, radical changes at active site residues completely conserved in CA isozymes with catalytic activity, make it unlikely that it has carbonic anhydrase activity. It shares properties in common with two other acatalytic CA isoforms, CA VIII and CA X. CA XI is most abundantly expressed in brain, and may play a general role in the central nervous system.

SEC1P (HGNC:44149): (secretory blood group 1, pseudogene) Predicted to enable galactoside 2-alpha-L-fucosyltransferase activity. Predicted to act upstream of or within protein glycosylation. [provided by Alliance of Genome Resources, Apr 2022]

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 10, 2024The c.16C>T (p.R6C) alteration is located in exon 1 (coding exon 1) of the CA11 gene. This alteration results from a C to T substitution at nucleotide position 16, causing the arginine (R) at amino acid position 6 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
