Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 06, 2023The c.1814G>A (p.R605H) alteration is located in exon 15 (coding exon 15) of the FAM13A gene. This alteration results from a G to A substitution at nucleotide position 1814, causing the arginine (R) at amino acid position 605 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
