Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 05, 2022The c.229C>T (p.R77C) alteration is located in exon 3 (coding exon 2) of the FAM222A gene. This alteration results from a C to T substitution at nucleotide position 229, causing the arginine (R) at amino acid position 77 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
