Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 22, 2023The c.490A>G (p.T164A) alteration is located in exon 5 (coding exon 3) of the CCDC122 gene. This alteration results from a A to G substitution at nucleotide position 490, causing the threonine (T) at amino acid position 164 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
