Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 12, 2024The c.134A>G (p.K45R) alteration is located in exon 4 (coding exon 2) of the CCDC122 gene. This alteration results from a A to G substitution at nucleotide position 134, causing the lysine (K) at amino acid position 45 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
