Genes affected

S100A6 (HGNC:10496): (S100 calcium binding protein A6) The protein encoded by this gene is a member of the S100 family of proteins containing 2 EF-hand calcium-binding motifs. S100 proteins are localized in the cytoplasm and/or nucleus of a wide range of cells, and involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation. S100 genes include at least 13 members which are located as a cluster on chromosome 1q21. This protein may function in stimulation of Ca2+-dependent insulin release, stimulation of prolactin secretion, and exocytosis. Chromosomal rearrangements and altered expression of this gene have been implicated in melanoma. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.86T>C (p.L29P) alteration is located in exon 2 (coding exon 1) of the S100A6 gene. This alteration results from a T to C substitution at nucleotide position 86, causing the leucine (L) at amino acid position 29 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
