Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 11, 2024The c.1839G>C (p.W613C) alteration is located in exon 21 (coding exon 20) of the ARMC8 gene. This alteration results from a G to C substitution at nucleotide position 1839, causing the tryptophan (W) at amino acid position 613 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
