Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 27, 2023The c.742C>T (p.P248S) alteration is located in exon 2 (coding exon 2) of the MFSD3 gene. This alteration results from a C to T substitution at nucleotide position 742, causing the proline (P) at amino acid position 248 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
