Submissions by phenotype

not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeFeb 21, 2022In 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. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. This variant has not been reported in the literature in individuals affected with ARMC9-related conditions. This variant is present in population databases (rs200925709, gnomAD 0.002%). This sequence change replaces histidine, which is basic and polar, with tyrosine, which is neutral and polar, at codon 7 of the ARMC9 protein (p.His7Tyr). -
