not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 04, 2023The c.508G>A (p.V170I) alteration is located in exon 7 (coding exon 4) of the FAM149A gene. This alteration results from a G to A substitution at nucleotide position 508, causing the valine (V) at amino acid position 170 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
