Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 27, 2022The c.1286C>G (p.T429R) alteration is located in exon 3 (coding exon 3) of the FAM155A gene. This alteration results from a C to G substitution at nucleotide position 1286, causing the threonine (T) at amino acid position 429 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
