Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_178460.3(SIRPD):c.308G>A(p.Arg103His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000991 in 1,614,054 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign 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. R103C) has been classified as Uncertain significance.

Ambry Genetics

Nov 19, 2022

The c.308G>A (p.R103H) alteration is located in exon 2 (coding exon 2) of the SIRPD gene. This alteration results from a G to A substitution at nucleotide position 308, causing the arginine (R) at amino acid position 103 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
