Endocrine Genomic Testing

The complete list of the Clinical Indications for endocrine-associated rare disorders can be found in the National Genomics Test Directory. Testing is provided by three of the seven Genomic Laboratory Hubs across England. WMRGL provides local, regional and national testing for the clinical indications listed below.

Patients’ samples should be sent to WMRGL; DNA will be extracted and testing will either take place in WMRGL or DNA will forwarded to our allocated provider according to NHS England’s instructions.

Please check the Test Directory eligibility criteria before your request any of these tests.

Referral forms can be found here  and for turnaround times please check here .

Alström syndrome

ALMS1 sequencing


Disorders of sex development



Gene Panel including genes associated with both 46,XX and 46,XY DSDs.


Copy number changes affecting the 11p13 WAGR syndrome region or the Xp21.2 NR0B1 region will not be detected by this gene panel method.  Please request a microarray for this testing (R146.1).


CYP21A2 cannot be analysed using this method due to the existence of a highly homologous pseudogene.  Please request R180 Congenital adrenal hyperplasia testing if CYP21A2 analysis is required.


Growth failure in early childhood (gene panel testing)



Indications for genetic testing of individuals for growth failure include:

  • A height/length more than 3 standard deviations (SDS) below the mean at the age of at least two years OR
  • The 3 following features:
    • Small for gestational age: ≤ -2SDS for gestational age
    • Postnatal growth failure: Height at 24 + 1 months ≤ -2SDS or height ≤ -2SDS below mid-parental target height
    • Low BMI: BMI ≤ -2SDS at 24 months


Please note this analysis includes BRCA2 and PALB2 which are also associated with inherited predisposition to breast and ovarian cancer.

Beckwith Wiedemann syndrome

Isolated hemihypertrophy or macroglossia


Congenital adrenal hypoplasia (adrenal hypoplasia congenital)



Pituitary hormone deficiency



Indications for genetic testing of causes of pituitary hormone deficiency include:

  • Deficiency of two or more pituitary hormones
  • Isolated growth hormone deficiency
  • Craniofacial midline defects including septo-optic dysplasia (SOD), pituitary stalk interruption syndrome (PSIS) or other structural pituitary gland abnormalities



Multi-locus imprinting disorder (MLID)

Tier 1 testing: (R417.1)

Methylation-sensitive MLPA (MS-MLPA) analysis of imprinted regions on chromosomes 6, 7, 11, 14, 15, 19 and 20.


Tier 2 testing (R417.2)

Small gene panel testing requires proband and maternal DNA to analyse as a duo. Tier 2 testing is available for patients with confirmed MLID. 




Congenital adrenal hyperplasia

CYP21A2 Sanger sequencing and MLPA


Testing of genes associated with rare forms of congenital adrenal hyperplasia is available as part of the R146.2 disorders of sex development panel.


Congenital adrenal hyperplasia carrier testing

Targeted testing of individuals with a known family history (R181.1 & R181.2), full gene screen of partners of known affected/carriers (R246.1)


Linkage for Congenital adrenal hyperplasia

Analysis of 5 microsatellite markers flanking the CYP21A2 gene.


Multiple endocrine neoplasia type 2

RET sequencing


Inherited phaeochromocytoma



Ambiguous genitalia presenting neonatally
