Genes affected

SERPINB7 (HGNC:13902): (serpin family B member 7) This gene encodes a member of a family of proteins which function as protease inhibitors. Expression of this gene is upregulated in IgA nephropathy and mutations have been found to cause palmoplantar keratoderma, Nagashima type. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2014]

The c.185C>G (p.T62S) alteration is located in exon 3 (coding exon 2) of the SERPINB7 gene. This alteration results from a C to G substitution at nucleotide position 185, causing the threonine (T) at amino acid position 62 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
