Variant summary

Our verdict is Benign. The variant received -8 ACMG points: 0P and 8B. BS1 BS2

The NM_000163.5(GHR):​c.-12+251_-12+264dupGTGTGTGTGTGTGT variant causes a intron change involving the alteration of a non-conserved nucleotide. It is difficult to determine the true allele frequency of this variant because it is of type INS_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

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

Our verdict: Benign. The variant received -8 ACMG points.

• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00853 (858/100564) while in subpopulation AFR AF = 0.012 (291/24222). AF 95% confidence interval is 0.0109. There are 20 homozygotes in GnomAd4. There are 373 alleles in the male GnomAd4 subpopulation. Median coverage is 0. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 20 AR,Unknown,AD gene
