Variant summary

Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2 PP3_Moderate

The NM_001394037.1(SHF):c.530T>C(p.Phe177Ser) variant causes a missense change. 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 Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. F177C) has been classified as Uncertain significance.

The c.335T>C (p.F112S) alteration is located in exon 3 (coding exon 2) of the SHF gene. This alteration results from a T to C substitution at nucleotide position 335, causing the phenylalanine (F) at amino acid position 112 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
