Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2PP3

The NM_001385875.1(ZFYVE27):c.242A>C(p.Asn81Thr) variant causes a missense change. The variant allele was found at a frequency of 0.000000684 in 1,461,892 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. N81S) has been classified as Uncertain significance.

Genes affected

ZFYVE27 (HGNC:26559): (zinc finger FYVE-type containing 27) This gene encodes a protein with several transmembrane domains, a Rab11-binding domain and a lipid-binding FYVE finger domain. The encoded protein appears to promote neurite formation. A mutation in this gene has been reported to be associated with hereditary spastic paraplegia, however the pathogenicity of the mutation, which may simply represent a polymorphism, is unclear.

The c.242A>C (p.N81T) alteration is located in exon 2 (coding exon 2) of the ZFYVE27 gene. This alteration results from a A to C substitution at nucleotide position 242, causing the asparagine (N) at amino acid position 81 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
