Genes affected
KLK12 (HGNC:6360): (kallikrein related peptidase 12) Kallikreins are a subgroup of serine proteases having diverse physiological functions. Growing evidence suggests that many kallikreins are implicated in carcinogenesis and some have potential as novel cancer and other disease biomarkers. This gene is one of the fifteen kallikrein subfamily members located in a cluster on chromosome 19. Alternate splicing of this gene results in three transcript variants encoding different isoforms.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 05, 2022The c.592G>T (p.G198C) alteration is located in exon 6 (coding exon 5) of the KLK12 gene. This alteration results from a G to T substitution at nucleotide position 592, causing the glycine (G) at amino acid position 198 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
