Genes affected
VCX2 (HGNC:18158): (variable charge X-linked 2) This gene belongs to the VCX/Y gene family, which has multiple members on both X and Y chromosomes that are expressed exclusively in male germ cells. The VCX gene cluster is polymorphic in terms of copy number; different individuals may have a different number of VCX genes. This gene contains two copies of a 30 nt tandem repeat. Deletion of a nearby member of this family was implicated in cognitive disability. [provided by RefSeq, Feb 2015]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 13, 2021The c.289G>A (p.E97K) alteration is located in exon 3 (coding exon 2) of the VCX2 gene. This alteration results from a G to A substitution at nucleotide position 289, causing the glutamic acid (E) at amino acid position 97 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
