This sequence change replaces lysine, which is basic and polar, with isoleucine, which is neutral and non-polar, at codon 7 of the FOCAD protein (p.Lys7Ile). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with FOCAD-related conditions. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
