Clinical Validity Scoring Notes and points

Variant/Case Evidence:

PMID 28280134- c.231G>C (p.Lys77Asn) variant found in parent and child with DBA. Patient cells were used with p.Lys77Asn showed pre-rRNA processing defects (0.5+0.5 = 1 pt)

PMID 30503522- Another report of the p.Lys77Asn variant in two individuals with DBA (unclear is these two are unrelated). These individuals also carry a deletion of RPS19 which is also associated with DBA and MOD is LOF for that gene. Given this potential for an alternative explanation, no points given.
