Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 11, 2021The c.587G>A (p.R196Q) alteration is located in exon 7 (coding exon 5) of the FAM193A gene. This alteration results from a G to A substitution at nucleotide position 587, causing the arginine (R) at amino acid position 196 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
