not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 22, 2023The c.754T>G (p.Y252D) alteration is located in exon 9 (coding exon 6) of the FAM149A gene. This alteration results from a T to G substitution at nucleotide position 754, causing the tyrosine (Y) at amino acid position 252 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
