Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2022The c.1967A>G (p.Y656C) alteration is located in exon 16 (coding exon 16) of the FAM13A gene. This alteration results from a A to G substitution at nucleotide position 1967, causing the tyrosine (Y) at amino acid position 656 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
