Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 20, 2023The c.143G>A (p.R48H) alteration is located in exon 4 (coding exon 2) of the CCDC77 gene. This alteration results from a G to A substitution at nucleotide position 143, causing the arginine (R) at amino acid position 48 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
