Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 28, 2023The c.203G>A (p.R68Q) alteration is located in exon 7 (coding exon 3) of the FAAP20 gene. This alteration results from a G to A substitution at nucleotide position 203, causing the arginine (R) at amino acid position 68 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
