Variant rs748792378 details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 4P and 1B. PM1PM5BS2_Supporting

The NM_000444.6(PHEX):c.1952G>A(p.Arg651Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000791 in 1,200,938 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 40 hemizygotes in GnomAD. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R651P) has been classified as Pathogenic.

Genes affected

PHEX (HGNC:8918): (phosphate regulating endopeptidase X-linked) The protein encoded by this gene is a transmembrane endopeptidase that belongs to the type II integral membrane zinc-dependent endopeptidase family. The protein is thought to be involved in bone and dentin mineralization and renal phosphate reabsorption. Mutations in this gene cause X-linked hypophosphatemic rickets. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 3 ACMG points.

PM1

In a hotspot region, there are 8 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 4 uncertain in NM_000444.6

PM5

Other missense variant is known to change same aminoacid residue: Variant chrX-22226495-G-C is described in ClinVar as [Pathogenic]. Clinvar id is 438548.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS2

High Hemizygotes in GnomAd4 at 2 XL geneVariant has number of hemizygotes lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
