Variant summary
Our verdict is Likely pathogenic. Variant got 9 ACMG points: 10P and 1B. PM2PP5_Very_StrongBP4
The NM_001312909.2(FAM111A):c.1706G>A(p.Arg569His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. 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 Likely pathogenic (★★).

Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Pathogenic. Following criteria are met: 0105 - The mechanism of disease for this gene is not clearly established. However, loss of function is an unlikely mechanism. (I) 0107 - This gene is associated with autosomal dominant disease. (I) 0200 - Variant is predicted to result in a missense amino acid change from arginine to histidine. (I) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0309 - An alternative amino acid change at the same position has been observed in gnomAD (v2) (16 heterozygotes, 0 homozygotes). (I) 0503 - Missense variant consistently predicted to be tolerated by multiple in silico tools or not conserved in placental mammals with a minor amino acid change. (SB) 0604 - Variant is not located in an established domain, motif, hotspot or informative constraint region. (I) 0801 - This variant has strong previous evidence of pathogenicity in unrelated individuals. This variant has been reported as likely pathogenic and pathogenic, and observed multiple times as de novo in individuals with Kenny-Caffey syndrome or nanophthalmos (ClinVar, DECIPHER, PMID: 32996714; PMID: 23684011). (SP) 1203 - This variant has been shown to be de novo in the proband (parental status confirmed, by trio analysis). (SP) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign -
The variant is not observed in the gnomAD v2.1.1 dataset. Missense changes are a common disease-causing mechanism. In silico tool predictions suggest damaging effect of the variant on gene or gene product (3Cnet: 0.97). Same nucleotide change resulting in same amino acid change has been previously reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000056810). Therefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline. -

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 569 of the FAM111A protein (p.Arg569His). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with Kenny-Caffey syndrome (PMID: 23684011, 23996431, 24635597, 24970356). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 56810). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt FAM111A protein function with a negative predictive value of 80%. For these reasons, this variant has been classified as Pathogenic. -
Not observed in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 28138333, 32765931, 24970356, 23996431, 24635597, 32996714, 33010201, 33258288, 23684011) -
