FGF8-related disorder Uncertain:1
The FGF8 c.550C>T variant is predicted to result in the amino acid substitution p.Arg184Cys. This variant in the homozygous condition was reported in an individual with hypogonadotropic hypogonadism, idiopathic (Men et al 2019. PubMed ID: 31748124). This variant is reported in 0.0047% of alleles in individuals of European (Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/10-103530271-G-A). A different variant affecting the same amino acid (p.Arg184His) was reported to negatively affect the proliferation of human cardiomyocytes (Zhou. 2020. PubMed ID: 32664970). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
