Variant summary

Our verdict is Pathogenic. The variant received 13 ACMG points: 13P and 0B. PM1PM2PM5PP2PP3_StrongPP5_Moderate

The NM_005360.5(MAF):​c.895C>A​(p.Arg299Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R299G) has been classified as Uncertain significance.

Genes affected
MAF (HGNC:6776): (MAF bZIP transcription factor) The protein encoded by this gene is a DNA-binding, leucine zipper-containing transcription factor that acts as a homodimer or as a heterodimer. Depending on the binding site and binding partner, the encoded protein can be a transcriptional activator or repressor. This protein plays a role in the regulation of several cellular processes, including embryonic lens fiber cell development, increased T-cell susceptibility to apoptosis, and chondrocyte terminal differentiation. Defects in this gene are a cause of juvenile-onset pulverulent cataract as well as congenital cerulean cataract 4 (CCA4). Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2010]

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 13 ACMG points.

PM1
In a hotspot region, there are 10 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 9 uncertain in NM_005360.5
PM2
Very rare variant in population databases, with high coverage;
PM5
Other missense variant is known to change same aminoacid residue: Variant chr16-79599008-G-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 1360617.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 22 curated pathogenic missense variants (we use a threshold of 10). The gene has 7 curated benign missense variants. Gene score misZ: 1.1779 (below the threshold of 3.09). Trascript score misZ: -0.24854 (below the threshold of 3.09). GenCC associations: The gene is linked to cerulean cataract, Fine-Lubinsky syndrome, cataract 21 multiple types, Ayme-Gripp syndrome, pulverulent cataract, cataract - microcornea syndrome.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.974
PP5
Variant 16-79599008-G-T is Pathogenic according to our data. Variant chr16-79599008-G-T is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 190235.Status of the report is criteria_provided_single_submitter, 1 stars.
