Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 01, 2024The c.305C>A (p.P102H) alteration is located in exon 1 (coding exon 1) of the MSGN1 gene. This alteration results from a C to A substitution at nucleotide position 305, causing the proline (P) at amino acid position 102 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
