Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 15, 2022The c.53G>A (p.C18Y) alteration is located in exon 2 (coding exon 1) of the FAM222A gene. This alteration results from a G to A substitution at nucleotide position 53, causing the cysteine (C) at amino acid position 18 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
