not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 29, 2024The c.663G>T (p.R221S) alteration is located in exon 8 (coding exon 7) of the CCDC149 gene. This alteration results from a G to T substitution at nucleotide position 663, causing the arginine (R) at amino acid position 221 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
