Genes affected
SPZ1 (HGNC:30721): (spermatogenic leucine zipper 1) This gene encodes a bHLH-zip transcription factor which functions in the mitogen-activate protein kinase (MAPK) signaling pathway. Because of its role in the upregulation of cell proliferation and tumorigenesis, this gene may serve as a target for Ras-induced tumor treatments. [provided by RefSeq, Oct 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 18, 2021The c.607G>A (p.A203T) alteration is located in exon 1 (coding exon 1) of the SPZ1 gene. This alteration results from a G to A substitution at nucleotide position 607, causing the alanine (A) at amino acid position 203 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
