Genes affected

PLCZ1 (HGNC:19218): (phospholipase C zeta 1) The protein encoded by this gene is a member of the phosphoinositide-specific phospholipase C family. Members in this family, classified into six isotypes that are tissue- and organ-specific, hydrolyze phosphatidylinositol 4,5-bisphosphate just before the phosphate group to yield diacylglycerol and inositol 1,4,5-trisphosphate. This protein localizes to the acrosome in spermatozoa and elicits Ca(2+) oscillations and egg activation during fertilization that leads to early embryonic development. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2012]

The c.1231A>T (p.T411S) alteration is located in exon 11 (coding exon 10) of the PLCZ1 gene. This alteration results from a A to T substitution at nucleotide position 1231, causing the threonine (T) at amino acid position 411 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
