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]

The c.301C>G (p.H101D) alteration is located in exon 3 (coding exon 2) of the VCX2 gene. This alteration results from a C to G substitution at nucleotide position 301, causing the histidine (H) at amino acid position 101 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
