Genes affected
THOP1 (HGNC:11793): (thimet oligopeptidase 1) The protein encoded by this gene is a kininase that uses zinc as a cofactor. The encoded oligopeptidase cleaves cytosolic peptides, making them unavailable for display on antigen-presenting cells. This protein also cleaves neuropeptides under 20 aa in length and can degrade beta-amyloid precursor protein to amyloidogenic peptides. [provided by RefSeq, Nov 2015]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 07, 2023The c.220A>G (p.T74A) alteration is located in exon 2 (coding exon 2) of the THOP1 gene. This alteration results from a A to G substitution at nucleotide position 220, causing the threonine (T) at amino acid position 74 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
