Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 11, 2023The c.2087G>T (p.R696L) alteration is located in exon 5 (coding exon 5) of the CHADL gene. This alteration results from a G to T substitution at nucleotide position 2087, causing the arginine (R) at amino acid position 696 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
