Genes affected

GHR (HGNC:4263): (growth hormone receptor) This gene encodes a member of the type I cytokine receptor family, which is a transmembrane receptor for growth hormone. Binding of growth hormone to the receptor leads to receptor dimerization and the activation of an intra- and intercellular signal transduction pathway leading to growth. Mutations in this gene have been associated with Laron syndrome, also known as the growth hormone insensitivity syndrome (GHIS), a disorder characterized by short stature. In humans and rabbits, but not rodents, growth hormone binding protein (GHBP) is generated by proteolytic cleavage of the extracellular ligand-binding domain from the mature growth hormone receptor protein. Multiple alternatively spliced transcript variants have been found for this gene.[provided by RefSeq, Jun 2011]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 ACMG points.

PVS1

Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.04225352 fraction of the gene. Cryptic splice site detected, with MaxEntScore 7.7, offset of 9, new splice context is: tgtgattgcacgtcctacAGgta. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Variant summary: GHR c.-11-1G>C is located in the untranscribed region upstream of the GHR gene region. Several computational tools predict a significant impact on normal splicing: Four predict the variant abolishes a 3' acceptor site. Two predict the variant creates a 3' acceptor site and two predict the variant strengthens this site. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 4e-05 in 251490 control chromosomes (gnomAD). This frequency is not significantly higher than estimated for a pathogenic variant in GHR causing Growth Hormone Insensitivity (4e-05 vs 0.0035), allowing no conclusion about variant significance. To our knowledge, no occurrence of c.-11-1G>C in individuals affected with Growth Hormone Insensitivity and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 1202951). Based on the evidence outlined above, the variant was classified as uncertain significance. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Has not been previously published as pathogenic or benign to our knowledge; In silico analysis, which includes splice predictors and evolutionary conservation, suggests this variant may impact gene splicing. In the absence of RNA/functional studies, the actual effect of this sequence change is unknown. -
