Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 01, 2024The c.1355C>A (p.P452H) alteration is located in exon 4 (coding exon 2) of the FAM222B gene. This alteration results from a C to A substitution at nucleotide position 1355, causing the proline (P) at amino acid position 452 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
