Variant summary

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

The NM_003135.3(SRP19):c.44T>C(p.Phe15Ser) variant causes a missense, splice region change. The variant was absent in control chromosomes in GnomAD project. 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 (★).

The c.44T>C (p.F15S) alteration is located in exon 2 (coding exon 2) of the SRP19 gene. This alteration results from a T to C substitution at nucleotide position 44, causing the phenylalanine (F) at amino acid position 15 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
