Genes affected
CSAD (HGNC:18966): (cysteine sulfinic acid decarboxylase) This gene encodes a member of the group 2 decarboxylase family. A similar protein in rodents plays a role in multiple biological processes as the rate-limiting enzyme in taurine biosynthesis, catalyzing the decarboxylation of cysteinesulfinate to hypotaurine. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Sep 2011]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 14, 2022The c.1333C>T (p.P445S) alteration is located in exon 16 (coding exon 15) of the CSAD gene. This alteration results from a C to T substitution at nucleotide position 1333, causing the proline (P) at amino acid position 445 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
