Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2022The c.698G>A (p.R233H) alteration is located in exon 8 (coding exon 8) of the FAM92A1 gene. This alteration results from a G to A substitution at nucleotide position 698, causing the arginine (R) at amino acid position 233 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
