Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2023The c.794T>C (p.M265T) alteration is located in exon 8 (coding exon 6) of the FAM114A1 gene. This alteration results from a T to C substitution at nucleotide position 794, causing the methionine (M) at amino acid position 265 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
