Genes affected

ZDHHC15 (HGNC:20342): (zinc finger DHHC-type palmitoyltransferase 15) The protein encoded by this gene belongs to the DHHC palmitoyltransferase family. Mutations in this gene are associated with mental retardatio X-linked type 91 (MRX91). Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.013141543).
• BP6: Variant X-75431511-A-T is Benign according to our data. Variant chrX-75431511-A-T is described in ClinVar as [Likely_benign]. Clinvar id is 445942.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.00119 (1302/1095911) while in subpopulation AMR AF= 0.0274 (961/35014). AF 95% confidence interval is 0.026. There are 9 homozygotes in gnomad4_exome. There are 358 alleles in male gnomad4_exome subpopulation. Median coverage is 29. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 3 XL gene
