Genes affected

FAM187A (HGNC:35153): (family with sequence similarity 187 member A) Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

GFAP (HGNC:4235): (glial fibrillary acidic protein) This gene encodes one of the major intermediate filament proteins of mature astrocytes. It is used as a marker to distinguish astrocytes from other glial cells during development. Mutations in this gene cause Alexander disease, a rare disorder of astrocytes in the central nervous system. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Oct 2008]

DNAAF19 (HGNC:32700): (coiled-coil domain containing 103) Enables protein homodimerization activity. Involved in axonemal dynein complex assembly; cilium movement; and determination of left/right symmetry. Predicted to be located in axoneme. Predicted to be part of outer dynein arm. Implicated in primary ciliary dyskinesia 17. [provided by Alliance of Genome Resources, Apr 2022]

DNAAF19 Gene-Disease associations (from GenCC):

• primary ciliary dyskinesia 17

  Inheritance: AR Classification: DEFINITIVE, STRONG, MODERATE Submitted by: ClinGen, Ambry Genetics, G2P, Labcorp Genetics (formerly Invitae)
• primary ciliary dyskinesia

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Likely_benign. The variant received -4 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.85).
