Description

The LHCGR c.32T>C variant is predicted to result in the amino acid substitution p.Leu11Pro. This variant has been reported in the homozygous state in two female siblings with empty follicle syndrome and has segregated with disease in this family (Zhang et al 2020. PubMed ID: 32860205). Functional studies showed that this variant has decreased expression and abnormal LHCGR glycosylation, and also causes ectopic subcellular localization and impaired cAMP levels (Zhang et al 2020. PubMed ID: 32860205). This variant is reported in 0.012% of alleles in individuals of Ashkenazi Jewish descent in gnomAD (http://gnomad.broadinstitute.org/variant/2-48982779-A-G). This variant is interpreted as likely pathogenic.
