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 -13 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.81).
• BP6: Variant 5-42424601-A-T is Benign according to our data. Variant chr5-42424601-A-T is described in ClinVar as [Benign]. Clinvar id is 3035850.Status of the report is no_assertion_criteria_provided, 0 stars.
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00393 (598/152272) while in subpopulation AFR AF = 0.014 (580/41576). AF 95% confidence interval is 0.013. There are 4 homozygotes in GnomAd4. There are 261 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 4 AR,Unknown,AD gene
