Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 24, 2024The c.652C>G (p.P218A) alteration is located in exon 7 (coding exon 6) of the SCAF1 gene. This alteration results from a C to G substitution at nucleotide position 652, causing the proline (P) at amino acid position 218 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
