Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 06, 2023The c.233G>A (p.R78Q) alteration is located in exon 4 (coding exon 2) of the FAM103A1 gene. This alteration results from a G to A substitution at nucleotide position 233, causing the arginine (R) at amino acid position 78 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
