Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 30, 2024The c.6761T>C (p.I2254T) alteration is located in exon 6 (coding exon 6) of the FAM186A gene. This alteration results from a T to C substitution at nucleotide position 6761, causing the isoleucine (I) at amino acid position 2254 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
