Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 30, 2021The c.2177G>A (p.R726Q) alteration is located in exon 9 (coding exon 9) of the CCDC142 gene. This alteration results from a G to A substitution at nucleotide position 2177, causing the arginine (R) at amino acid position 726 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
