Genes affected
SPECC1 (HGNC:30615): (sperm antigen with calponin homology and coiled-coil domains 1) The protein encoded by this gene belongs to the cytospin-A family. It is localized in the nucleus, and highly expressed in testis and some cancer cell lines. A chromosomal translocation involving this gene and platelet-derived growth factor receptor, beta gene (PDGFRB) may be a cause of juvenile myelomonocytic leukemia. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Aug 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 16, 2023The c.47G>T (p.G16V) alteration is located in exon 1 (coding exon 1) of the SPECC1 gene. This alteration results from a G to T substitution at nucleotide position 47, causing the glycine (G) at amino acid position 16 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
