not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Nov 29, 2023 | The c.1043T>C (p.L348P) alteration is located in exon 7 (coding exon 7) of the MYBPH gene. This alteration results from a T to C substitution at nucleotide position 1043, causing the leucine (L) at amino acid position 348 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
