Genes affected
THTPA (HGNC:18987): (thiamine triphosphatase) This gene encodes an enzyme which catalyzes the biosynthesis of thiamine disphophate (vitamin B1) by hydrolysis of thiamine triphosphate. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2011]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Feb 27, 2023 | The c.562G>C (p.E188Q) alteration is located in exon 2 (coding exon 2) of the THTPA gene. This alteration results from a G to C substitution at nucleotide position 562, causing the glutamic acid (E) at amino acid position 188 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
