Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 16, 2022The c.3532G>A (p.A1178T) alteration is located in exon 4 (coding exon 4) of the FAM205A gene. This alteration results from a G to A substitution at nucleotide position 3532, causing the alanine (A) at amino acid position 1178 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
