Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV004789919 SCV005398342 likely pathogenic Coffin-Lowry syndrome 2024-10-10 criteria provided, single submitter clinical testing Based on the classification scheme VCGS_Germline_v1.3.5, this variant is classified as Likely Pathogenic. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with Coffin-Lowry syndrome (MIM#303600) and intellectual developmental disorder, X-linked 19 (MIM#300844). (I) 0110 - This gene is associated with X-linked dominant disease. Females may be severely affected or very mild, with some affected males having inherited their variants from unaffected mothers (PMIDs: 19888300, 16879200). (I) 0115 - Variants in this gene are known to have variable expressivity, with intrafamilial variability reported (PMID: 32858545). (I) 0200 - Variant is predicted to result in a missense amino acid change from asparagine to lysine. This variant is located at the first base of an exon. (I) 0253 - This variant is hemizygous. (I) 0301 - Variant is absent from gnomAD (v2, v3 and v4). (SP) 0501 - Missense variant consistently predicted to be damaging by multiple in silico tools or highly conserved with a major amino acid change. Abnormal splicing is not predicted and the nucleotide is poorly conserved . (SP) 0603 - Missense variant in the protein kinase domain that is highly intolerant to missense variation (high constraint region in DECIPHER, gnomAD). (SP) 0704 - Another missense variant comparable to the one identified in this case has limited previous evidence for pathogenicity. p.(Asn198Asp) was observed in a male with Coffin-Lowry syndrome (PMID: 37804371). (SP) 0807 - This variant has no previous evidence of pathogenicity. (I) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 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
