Illumina Clinical Services Laboratory,Illumina RCV000017998 SCV000915177 pathogenic Factor XIII, A subunit, deficiency of 2017-09-12 criteria provided, single submitter clinical testing The F13A1 c.980G>A (p.Arg327Gln) missense variant has been reported in at least four studies and is found in a total of nine individuals with symptoms consistent with factor XIII subunit A deficiency. Four of these affected individuals are from the same family, including three brothers, two of whom died neonatally due to intracranial hemorrhages, with the variant in a homozygous state, and one relative in a compound heterozygous state (Mikkola et al. 1996). Five unrelated affected individuals, all with factor XIII subunit A deficiency, have also been reported with the variant in a compound heterozygous state (Gómez García et al. 2001; Katona et al. 2014; Ivaškevičius et al. 2017). The variant is also found in nine unaffected carriers from the same family as the affected homozygous brothers. Segregation analysis revealed that the p.Arg327Gln variant segregated with disease in this family (Mikkola et al. 1996). The p.Arg327Gln variant was absent from at least 25 controls and is reported at a frequency of 0.00002 in the total population of the Genome Aggregation Database. Based on the collective evidence, the p.Arg327Gln variant is classified as pathogenic for factor XIII subunit A deficiency. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population.
