Genes affected

TESMIN (HGNC:7446): (testis expressed metallothionein like protein) Metallothionein proteins are highly conserved low-molecular-weight cysteine-rich proteins that are induced by and bind to heavy metal ions and have no enzymatic activity. They may play a central role in the regulation of cell growth and differentiation and are involved in spermatogenesis. This gene encodes a metallothionein-like protein which has been shown to be expressed differentially in mouse testis and ovary. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The c.68G>T (p.S23I) alteration is located in exon 2 (coding exon 1) of the TESMIN gene. This alteration results from a G to T substitution at nucleotide position 68, causing the serine (S) at amino acid position 23 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
