not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2022The c.3355C>T (p.L1119F) alteration is located in exon 4 (coding exon 4) of the FAM205A gene. This alteration results from a C to T substitution at nucleotide position 3355, causing the leucine (L) at amino acid position 1119 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
