Mendeliome v0.13683 DUSP6 Krithika Murali changed review comment from: PMID: 23643382 Miraoui et al 2013 - - candidate gene study for genes in the FGFR1 pathway that may be associated with CHH, either as causative genes or disease modifiers. A cohort of 386 CHH individuals and 155 unaffected controls of European descent. A number of affected individuals included in this cohort already had known causative variants in CHH-associated genes. The coding exons and proximal introns (≥15 bp from splice sites) of FGF17, FGF18, IL17RD, DUSP6, SPRY2, SPRY4, and FLRT3 were amplified by PCR and determined by direct sequencing.

Summary of DUSP6 variants identified in this study
c.229 T>A p.(Phe77Ile) - absent gnomAD v2 and v3
c.545C>T p.(Ser182Phe) - 203 hets gnomad v2, 137 hets and 1 hom - v3 - identified in conjunction with FGFR1 variant in this individual
c.566A>G p.Asn189Ser - v2 57 hets, v3 29 hets (another individual identified with this variant and an SPRY4 variant)
c.1037C>T p.Thr346Met - 81 hets v2, 27 hets and 1 hom v3 (identified in conjunction with SPRY4 variant

PMID: 23643382 - Dusp6 null mouse model reportedly has craniofacial defects and hearing defects, but no mention of hypogonadotropic hypogonadism. In 5 unrelated individuals with congenital hypogonadotropic hypogonadism 4 heterozygous missense were identified. In 3 of the probands, the DUSP6 mutation was accompanied by a heterozygous missense mutation in another HH-associated gene. 3 of the 4 variants have subpopulation allele frequencies in gnomAD v2.1 that are higher than expected for a dominant condition: p.Thr346Met (AJ AF 0.002797), p.Ser182Phe (NFE AF 0.001396), p.Asn189Ser (NFE AF 0.0003641). No functional assays were conducted.

PMID: 32389901 - 6 unrelated male Chinese Kallman syndrome cases with 4 DUSP6 missense variants. 2 of 4 variants have East Asian allele frequencies in gnomAD v2.1 that are higher than expected for a dominant condition: p.Pro188Leu (EAS AF 0.001203), p.Arg83Gln (EAS AF 0.001129).

Mendeliome v0.13683 DUSP6 Krithika Murali changed review comment from: 1 study cited by OMIM (Miraoui et al 2013) - heterozygous variants in 5 unrelated individuals with congenital hypogonadotrophic hypogonadism (CHH). 4/5 variants highly prevalent in healthy population and/or in conjunction with variants in other genes either known to be associated with CHH or possibly associated. No additional studies published since this paper.
