Martina Owens (Exeter Genetics Laboratory, Royal Devon and Exeter NHS Foundation Trust)

Green List (high evidence)

Pathogenic variants in this gene are the most common cause of Hypophosphatemic rickets (PMID: 19219621)
Created: 28 Jan 2019, 10:38 a.m.

Mode of inheritance
X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males)

Phenotypes
Hypophosphatemia; rickets

Variants in this GENE are reported as part of current diagnostic practice

Ivone Leong (Genomics England Curator)

As discussed in the GMS Endocrinology Specialist Test Group webex call 28th Jan 2019: The Specialist Test Group agreed that there is enough evidence to rate this gene green.
Created: 29 Jan 2019, 11:44 a.m.
PHEX is a green gene on the Skeletal dysplasia panel (Version 1.129).
Created: 30 Nov 2018, 3 p.m.
Comment when marking as ready: OMIM has confirmed that PHEX is associated with hypophosphataemic rickets; however, no phenotype is listed wih PHEX on Gene2Phenotype. One study reported 20 patients from 12 unrelated familes with variants in this gene with this phenotype (PMID: 29505567). Another study reported variants in 21 probands (PMID: 22695891). More than 3 families reported with variants in this gene diagnosed with this phenotype on OMIM. Also, based on the review by Sian Ellard (University of Exeter Medical School).
