Genes affected

FXYD2 (HGNC:4026): (FXYD domain containing ion transport regulator 2) This gene encodes a member of the FXYD family of transmembrane proteins. This particular protein encodes the sodium/potassium-transporting ATPase subunit gamma. Mutations in this gene have been associated with Renal Hypomagnesemia-2. Alternatively spliced transcript variants have been described. Read-through transcripts have been observed between this locus and the upstream FXYD domain-containing ion transport regulator 6 (FXYD6, GeneID 53826) locus.[provided by RefSeq, Feb 2011]

FXYD6-FXYD2 (HGNC:39978): (FXYD6-FXYD2 readthrough) This locus represents naturally occurring read-through transcription between the neighboring FXYD domain-containing ion transport regulator 6 (GeneID 53826) and sodium/potassium-transporting ATPase subunit gamma (GeneID 486) genes on chromosome 11. One read-through transcript produces a fusion protein that shares sequence identity with each individual gene product, while another read-through transcript encodes a protein that has a distinct C-terminus and only shares sequence identity with the upstream locus (GeneID 53826).

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
