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

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.8).
• BP6: Variant X-22032995-C-T is Benign according to our data. Variant chrX-22032995-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 1987440.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS2: High Hemizygotes in GnomAdExome4 at 18 XL gene
