Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 25, 2024The c.227G>A (p.R76Q) alteration is located in exon 2 (coding exon 2) of the CCDC136 gene. This alteration results from a G to A substitution at nucleotide position 227, causing the arginine (R) at amino acid position 76 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
