Genes affected
CTSV (HGNC:2538): (cathepsin V) The protein encoded by this gene, a member of the peptidase C1 family, is a lysosomal cysteine proteinase that may play an important role in corneal physiology. This gene is expressed in colorectal and breast carcinomas but not in normal colon, mammary gland, or peritumoral tissues, suggesting a possible role for this gene in tumor processes. Alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Jan 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 15, 2024The c.443A>C (p.E148A) alteration is located in exon 5 (coding exon 4) of the CTSV gene. This alteration results from a A to C substitution at nucleotide position 443, causing the glutamic acid (E) at amino acid position 148 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
