Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 10, 2024The c.1322C>A (p.P441H) alteration is located in exon 6 (coding exon 6) of the MFSD9 gene. This alteration results from a C to A substitution at nucleotide position 1322, causing the proline (P) at amino acid position 441 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
