Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 10, 2024The c.688C>T (p.P230S) alteration is located in exon 8 (coding exon 6) of the FAM193A gene. This alteration results from a C to T substitution at nucleotide position 688, causing the proline (P) at amino acid position 230 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
