Diagnostics Lab (ASPIRE), CSIR - Centre for Cellular and Molecular Biology RCV000856819 SCV000998949 uncertain significance Metabolic acidosis; Renal tubular acidosis; Rickets 2019-11-09 criteria provided, single submitter clinical testing A role of this CA1 gene in renal tubular acidosis was suggested earlier, however no disorder has been associated with this gene till date (Shapira et al. J Clin Invest 1974). Another gene of this family (CA2) is known to cause autosomal recessive osteopetrosis with renal tubular acidosis (MIM#259730). The c.368_369del variant is present in publicly available databases like Exome Aggregation Consortium (ExAC), Genome Aggregation Database (gnomAD) and dbSNP only in heterozygous state (minor allele frequency < 0.00001). The variant is not present in our in-house exome database. The variant was not reported to OMIM, ClinVar and Human Genome Mutation Database (HGMD) in any other affected individuals. In-silico pathogenicity prediction programs like MutationTaster2, CADD etc. predicted this variant as likely deleterious.
