Variant summary

Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM2PP3_Strong

The NM_018441.6(PECR):c.427T>G(p.Tyr143Asp) variant causes a missense, splice region change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000251 in 1,595,700 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 1/1 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (★).

Nov 10, 2022

The c.427T>G (p.Y143D) alteration is located in exon 4 (coding exon 4) of the PECR gene. This alteration results from a T to G substitution at nucleotide position 427, causing the tyrosine (Y) at amino acid position 143 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
