Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2022The c.238A>C (p.S80R) alteration is located in exon 3 (coding exon 3) of the CCDC138 gene. This alteration results from a A to C substitution at nucleotide position 238, causing the serine (S) at amino acid position 80 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
