Genes affected

INCA1 (HGNC:32224): (inhibitor of CDK, cyclin A1 interacting protein 1) Enables cyclin binding activity; cyclin-dependent protein serine/threonine kinase inhibitor activity; and identical protein binding activity. Acts upstream of or within negative regulation of cyclin-dependent protein serine/threonine kinase activity. Located in cytoplasm and nuclear body.

The c.115C>T (p.R39C) alteration is located in exon 5 (coding exon 2) of the INCA1 gene. This alteration results from a C to T substitution at nucleotide position 115, causing the arginine (R) at amino acid position 39 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
