Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 13, 2024The c.97A>T (p.R33W) alteration is located in exon 1 (coding exon 1) of the FAM150A gene. This alteration results from a A to T substitution at nucleotide position 97, causing the arginine (R) at amino acid position 33 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
