Genes affected

SPINK4 (HGNC:16646): (serine peptidase inhibitor Kazal type 4) Predicted to enable serine-type endopeptidase inhibitor activity. Predicted to be involved in negative regulation of endopeptidase activity and response to xenobiotic stimulus. Predicted to be located in extracellular region. [provided by Alliance of Genome Resources, Apr 2022]

SPINK4 links:

BAG1 (HGNC:937): (BAG cochaperone 1) The oncogene BCL2 is a membrane protein that blocks a step in a pathway leading to apoptosis or programmed cell death. The protein encoded by this gene binds to BCL2 and is referred to as BCL2-associated athanogene. It enhances the anti-apoptotic effects of BCL2 and represents a link between growth factor receptors and anti-apoptotic mechanisms. Multiple protein isoforms are encoded by this mRNA through the use of a non-AUG (CUG) initiation codon, and three alternative downstream AUG initiation codons. A related pseudogene has been defined on chromosome X. [provided by RefSeq, Feb 2010]

The c.248A>G (p.D83G) alteration is located in exon 4 (coding exon 4) of the SPINK4 gene. This alteration results from a A to G substitution at nucleotide position 248, causing the aspartic acid (D) at amino acid position 83 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
