Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 15, 2024The c.5T>C (p.M2T) alteration is located in exon 2 (coding exon 2) of the FAM21A gene. This alteration results from a T to C substitution at nucleotide position 5, causing the methionine (M) at amino acid position 2 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
