Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 22, 2023The c.1730G>A (p.R577Q) alteration is located in exon 12 (coding exon 12) of the KCTD19 gene. This alteration results from a G to A substitution at nucleotide position 1730, causing the arginine (R) at amino acid position 577 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
