Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 09, 2024The c.1820G>A (p.C607Y) alteration is located in exon 21 (coding exon 20) of the ARMC8 gene. This alteration results from a G to A substitution at nucleotide position 1820, causing the cysteine (C) at amino acid position 607 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
