Genes affected

SLC25A46 (HGNC:25198): (solute carrier family 25 member 46) This gene encodes a mitochondrial solute carrier protein family member. It functions in promoting mitochondrial fission, and prevents the formation of hyperfilamentous mitochondria. Mutation of this gene results in neuropathy and optic atrophy.

TMEM232 (HGNC:37270): (transmembrane protein 232) Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.8).
• BP6: Variant 5-110738678-T-C is Benign according to our data. Variant chr5-110738678-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 1187279.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00669 (1018/152172) while in subpopulation AFR AF= 0.0238 (989/41528). AF 95% confidence interval is 0.0226. There are 16 homozygotes in gnomad4. There are 465 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 16 AR gene
