Genes affected

FANCM (HGNC:23168): (FA complementation group M) The Fanconi anemia complementation group (FANC) currently includes FANCA, FANCB, FANCC, FANCD1 (also called BRCA2), FANCD2, FANCE, FANCF, FANCG, FANCI, FANCJ (also called BRIP1), FANCL, FANCM and FANCN (also called PALB2). The previously defined group FANCH is the same as FANCA. Fanconi anemia is a genetically heterogeneous recessive disorder characterized by cytogenetic instability, hypersensitivity to DNA crosslinking agents, increased chromosomal breakage, and defective DNA repair. The members of the Fanconi anemia complementation group do not share sequence similarity; they are related by their assembly into a common nuclear protein complex. This gene encodes the protein for complementation group M. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2015]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.4784C>A (p.P1595H) alteration is located in exon 20 (coding exon 20) of the FANCM gene. This alteration results from a C to A substitution at nucleotide position 4784, causing the proline (P) at amino acid position 1595 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces proline, which is neutral and non-polar, with histidine, which is basic and polar, at codon 1595 of the FANCM protein (p.Pro1595His). This variant is present in population databases (rs750818919, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with FANCM-related conditions. ClinVar contains an entry for this variant (Variation ID: 456272). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
