Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2022The c.847G>A (p.V283I) alteration is located in exon 7 (coding exon 6) of the FAHD2B gene. This alteration results from a G to A substitution at nucleotide position 847, causing the valine (V) at amino acid position 283 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
