Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 07, 2024The c.496C>T (p.P166S) 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 496, causing the proline (P) at amino acid position 166 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
