Genes affected
CENPT (HGNC:25787): (centromere protein T) The centromere is a specialized chromatin domain, present throughout the cell cycle, that acts as a platform on which the transient assembly of the kinetochore occurs during mitosis. All active centromeres are characterized by the presence of long arrays of nucleosomes in which CENPA (MIM 117139) replaces histone H3 (see MIM 601128). CENPT is an additional factor required for centromere assembly (Foltz et al., 2006 [PubMed 16622419]).[supplied by OMIM, Mar 2008]
TSNAXIP1 (HGNC:18586): (translin associated factor X interacting protein 1) Predicted to be involved in cell differentiation and spermatogenesis. Predicted to be located in perinuclear region of cytoplasm. Predicted to be active in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 30, 2022The c.1558C>G (p.R520G) alteration is located in exon 15 (coding exon 12) of the CENPT gene. This alteration results from a C to G substitution at nucleotide position 1558, causing the arginine (R) at amino acid position 520 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
