Clinical Validity Scoring Notes and points

Variant/Case Evidence:

PMID 32581362- Variant reported in one individual with [Stem cell/Myeloid Disorder]: c.860_863dupTCTG p.(Trp288Cysfs*12). (1 pt)

PMID 31570891- Variants reported in two individuals with DC: c.532G>C p.D178H (0.5pts), c.538_540del p.D180del (no points; gnomAD v4 grpmax AF=0.05%); Mice with altered NMP1 showed clinical features of DC (2 pts) (2.5 pts)
