Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 27, 2022The c.1706G>A (p.R569Q) alteration is located in exon 3 (coding exon 3) of the CHADL gene. This alteration results from a G to A substitution at nucleotide position 1706, causing the arginine (R) at amino acid position 569 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
