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]
PHEX-AS1 (HGNC:40445): (PHEX antisense RNA 1)

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

BP6
Variant X-22168307-TG-T is Benign according to our data. Variant chrX-22168307-TG-T is described in ClinVar as [Benign]. Clinvar id is 1559183.Status of the report is criteria_provided_single_submitter, 1 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.
