Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 11, 2024The c.6779T>C (p.F2260S) 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 6779, causing the phenylalanine (F) at amino acid position 2260 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
