Genes affected

CA3 (HGNC:1374): (carbonic anhydrase 3) Carbonic anhydrase III (CAIII) is a member of a multigene family (at least six separate genes are known) that encodes carbonic anhydrase isozymes. These carbonic anhydrases are a class of metalloenzymes that catalyze the reversible hydration of carbon dioxide and are differentially expressed in a number of cell types. The expression of the CA3 gene is strictly tissue specific and present at high levels in skeletal muscle and much lower levels in cardiac and smooth muscle. A proportion of carriers of Duchenne muscle dystrophy have a higher CA3 level than normal. The gene spans 10.3 kb and contains seven exons and six introns. [provided by RefSeq, Oct 2008]

Ambry Genetics

Dec 27, 2022

The c.28C>T (p.H10Y) alteration is located in exon 1 (coding exon 1) of the CA3 gene. This alteration results from a C to T substitution at nucleotide position 28, causing the histidine (H) at amino acid position 10 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
