Growth failure in early childhood

Gene: NLRP5

Submitted on behalf of NHS GMS "This gene does not go on the panel as linked to MLID and suggest separate panel for this. Genes NLRP5, NLRP7, PAD16, NLRP2 & KHDC3L"

Panel Version: 1.100

After NHS Genomic Medicine Service consideration, the rating of this gene has not been changed.

Green List (high evidence)

Comment on mode of inheritance: Review from Eamonn Maher: I think it would be better that these are maternal effect genes for which biallelic variants in a healthy women cause a reproductive phenotype that may include miscarriage, hydatidiform mole or children with a congenital imprinting disorder

Panel Version: 1.59

Comment on list classification: Based on review from Professor Karen Temple (Clinical Genetics, University Hospital Southampton NHS Foundation Trust) for the involvement of NLRP5 variants in Multi Locus Imprinting Disturbance

Panel Version: 1.52

Green List (high evidence)

A number of patients with IUGR and failure of catch up have an imprinting error (withiin the spectrum of Silver Russell syndrome, temple syndrome) that is caused by mutations in NLRP5 in the MOTHER of the patient. Note that LOF mutations (homozygous or heterozygous mutations) identified in the mother would lead to further patient testing for multilocus imprinting disturbance through methylation testing.
