Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2024The c.439G>C (p.V147L) alteration is located in exon 3 (coding exon 2) of the FAHD2B gene. This alteration results from a G to C substitution at nucleotide position 439, causing the valine (V) at amino acid position 147 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
