Genes affected
GH1 (HGNC:4261): (growth hormone 1) The protein encoded by this gene is a member of the somatotropin/prolactin family of hormones which play an important role in growth control. The gene, along with four other related genes, is located at the growth hormone locus on chromosome 17 where they are interspersed in the same transcriptional orientation; an arrangement which is thought to have evolved by a series of gene duplications. The five genes share a remarkably high degree of sequence identity. Alternative splicing generates additional isoforms of each of the five growth hormones, leading to further diversity and potential for specialization. This particular family member is expressed in the pituitary but not in placental tissue as is the case for the other four genes in the growth hormone locus. Mutations in or deletions of the gene lead to growth hormone deficiency and short stature. [provided by RefSeq, Jul 2008]

Significance:Pathogenic
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The best available variant frequency is uninformative because there are too few occurrences in population data. Found in at least one symptomatic patient. Conflicting predictions of the effect on the protein. Damaging to protein function(s) relevant to disease mechanism. Very strong co-segregation with disease in affected individuals from multiple families. -

Significance:Pathogenic
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 209 of the GH1 protein (p.Arg209His). This variant is present in population databases (rs137853223, gnomAD 0.01%). This missense change has been observed in individual(s) with clinical features of autosomal dominant growth hormone deficiency (PMID: 17785368, 29739035, 33729509, 34006472, 34589056). It has also been observed to segregate with disease in related individuals. This variant is also known as p.Arg183His. ClinVar contains an entry for this variant (Variation ID: 15983). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). For these reasons, this variant has been classified as Pathogenic. -
