Variant 1-37799577-C-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2PP3

The ENST00000373045.11(MANEAL):c.748C>T(p.His250Tyr) variant causes a missense change. The variant allele was found at a frequency of 0.00000205 in 1,460,898 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. H250R) has been classified as Uncertain significance.

The c.748C>T (p.H250Y) alteration is located in exon 4 (coding exon 4) of the MANEAL gene. This alteration results from a C to T substitution at nucleotide position 748, causing the histidine (H) at amino acid position 250 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
